Hi!
I have an issue with a usb to sata adapter when much high speed data is
sent. If I erase my 4Tb SSD disk connected to the usb to sata interface
with a "slower" /dev/urandom it works, but if I exchanges this to
/dev/zero the disk is after a while disconnected.
For logs from udev and more debug attempts see:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1886172
Description:
When the speed of data with a usb disk device is too high, the probes
that check if the disk still exists is missed. This makes the disk to be
unmounted and is remounted with an other drive letter (/dev/sdX). If
this disk is the root ("/"), the computer hangs.
A usb SSD-disk (4 TB) connected to a USB port reproduce this bug easily.
This has never happened with a mechanical USB-drive.
Symptoms and how to reproduce:
1) (Disk mounted as root) Computer hangs. Only way to get started again
is a hard reset.
2) (Erasing disk, not mounted as root) If you erase a disk with dd ("dd
if=/dev/zero of=/dev/sdX"), the disk disappears from the mounted list
and reappears as an other drive letter. In my case the data is
redirected to /dev/null and the fans speed up. The apparent data
transfer speed is also increased. Usually this happens after about 45 to
60 minutes.
3) Fill RAM with programs and make sure the swap to this disk is used.
Bug found in:
$ uname -a
Linux pb-189b1884 5.4.0-40-generic #44-Ubuntu SMP Tue Jun 23 00:01:04
UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
$ cat /proc/version_signature
Ubuntu 5.4.0-40.44-generic 5.4.44
Hardware:
Tested with slower and faster computers. Tested directly connected to a
computer and via a hub. They all reproduce this bug.
Workaround:
None found.

Can you provide kernel logs? Odds are the disk disconnects itself as it
takes too much power or something.

That's a really old kernel, any chance you can try 5.8?

udev-kernel logs can be found:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1886172
I have tested the usb to sata adapter directly connected to a computer
and connected to a externally powered usb hub. The bug behavior is the same.
One time when I tested the whole usb hub disconnected. I have a usb to
ethernet connected to it too. It vanished and appeared again. Doubt it
is power. The externally powered hub can deliver 4A, but I hope the usb
to sata only takes 2A.

I'm downloading from
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git. Will
test it soon.

udev logs do not help, can you do, from a command line:
sudo dmesg -c # clears the kernel log
<do your testing>
dmesg > kernel_log.txt
and send us the kernel_log.txt file?

I bet the adapter can't handle the issue here, writing a lot of data to
flash does take a lot of power.

If the whole hub disconnected, that is a _huge_ hint it's a power issue,
the operating system can not do that on its own.

The bug report doesn't seem to contain any dmesg kernel logs showing
what happens when the problem occurs.
Also, the bug report indicates that you started to do a bisection
looking for the kernel version where the problem first appears, but
there's no mention of the final result.
The bug report also indicates that one of your tests involves copying
/dev/zero to a mounted disk device! That is highly likely to crash the
kernel regardless of what the hardware does. What happens if you
unmount the disk before running the test?

I'm compiling the latest kernel to supply the kernel logs when done
testing. It takes a while.

There were no result. For an unknown reason I haven't the bug behavior
in the 4.15 series of the kernel (Ubuntu Mate Bionic), but when I tried
later I had. Maybe it was when I ran Ubuntu Mate Focal with 4.15 series
of kernel that triggered the bug.
It was a failed attempt to iterate to the kernel version that worked.
It is the same hardware.

The ssd disk contains no partition data. It is not mounted.

'make localmodconfig' is your friend. Should make a kernel that builds
in 5-10 minutes at most depending on your system.

Hi Greg,
A lot of lengthy testing and the result seem promising. Here is
something to think about and why the result is as it is.
Three kernels was tested with and without
'GRUB_CMDLINE_LINUX_DEFAULT="usb-storage.quirks=174c:55aa:u"'. This is
shortened with and without quirks.
The following kernel fails WITH quirks: (all tested)
Linux 5.8.0+ #1 SMP Tue Aug 11 21:31:01 CEST 2020 x86_64 x86_64 x86_64
GNU/Linux (dmesg attached)
Linux 5.4.0-39-generic #43-Ubuntu SMP Fri Jun 19 10:28:31 UTC 2020
x86_64 x86_64 x86_64 GNU/Linux
Linux 5.4.0-37-generic #41-Ubuntu SMP Wed Jun 3 18:57:02 UTC 2020 x86_64
x86_64 x86_64 GNU/Linux
The following kernel fails WITHOUT quirks:
Linux 5.4.0-37-generic #41-Ubuntu SMP Wed Jun 3 18:57:02 UTC 2020 x86_64
x86_64 x86_64 GNU/Linux
The following kernels succeed WITHOUT quirks:
Linux 5.8.0+ #1 SMP Tue Aug 11 21:31:01 CEST 2020 x86_64 x86_64 x86_64
GNU/Linux
Linux 5.4.0-39-generic #43-Ubuntu SMP Fri Jun 19 10:28:31 UTC 2020
x86_64 x86_64 x86_64 GNU/Linux
The same hardware and Ubuntu Mate Focal was used without modification.
Best regards,
Patrik

Your device disconnected itself from the bus, that is an electrical
thing that the kernel can not control/prevent/change.

And now it came back.
So I really think this device is just sucking up too much power and
eventually the hub disconnects it (or it disconnects itself by dropping
the voltage too low) and then adds itself again.
If you write data "slower" to it, it's fine, but by writing 0's to your
device, it's constantly hammered and that's the hardest thing for a
flash device to handle (flash starts out at all bits set and then drops
them as needed to 0, so you are asking for the most work possible to be
done by the flash chips.)
It might be better to just buy a different disk drive :)
sorry,

Hi Greg,
Thank you for debugging the issue!
Is there a way to set a speed limit to the device? I mean like setting
the usb-quirks. (i.e. usb-storage.quirks=174c:55aa:u)
Instead of buying a new enclosing for the drive... :(
Best regards,
Patrik

You can try setting usb-storage.quirks=174c:55aa:g or :m. They will
slow down the data transfer rates. The :g flag is used by the uas
driver and the :m flag is used by usb-storage.

Hi Alan,
Unfortunately the options you suggested didn't help.
The patch below works and is tested with Ubuntu kernel 5.4.0.47.50.
I have stress tested the usb system. To the USB is now seven mechanical
hard disks and two ssd disks connected. Six processes are at the same
time writing random data to the disks. One of them is to the ssd disk I
couldn't write data to before without it failed. Also the other usb-ssd
disk is my root partition.
Before I applied the patch, my root partition sometimes failed to be
kept mounted. Now I have not had any crashes.
This is a quick fix for hard disks, but working. It continued to work
when I started three virtualbox guests and let them also do work. The
guests' hard disks is on my usb-root partition.
It doesn't work if I also use my usb2ethernet adapter (ID 2001:4a00
D-Link Corp.), although my root partition and two randomize tests
survived. Maybe a much larger timeout in this case will help? But this I
don't find as a good solution.
The behavior is the same on the other (much slower) computer with a
different usb hub. I have also tested it with exactly the same setup as
earlier, with no mechanical hard disks, and it works with the patch and
not without it.
Any suggestion on how to solve this? In a good way.
Best regards,
Patrik

Is there any way you can capture a usbmon trace that shows the problem?

What happens if you leave these two lines unchanged and increase only
the HUB_DEBOUNCE_TIMEOUT value?

Dear Alan,
After long time testing it seems that changing the TIMEOUT values did
help somewhat, but not completely.
I tested two SSD and wrote to them at the same time:
# dd if=/dev/zero of=/dev/sdd bs=$((10*1024*1024))
# dd if=/dev/zero of=/dev/sdg bs=$((10*1024*1024)) # different bash terminal
The synchronize write gives a lot of errors as the log below (1) shows
Running big with blocks in synchronized mode gives the same kind of error:
# dd if=/dev/zero of=/dev/sdi bs=$((10*1024*1024)) oflag=dsync # this is
another SSD bought for this test
dd: error writing '/dev/sdi': Input/output error
9+0 records in
8+0 records out
83886080 bytes (84 MB, 80 MiB) copied, 185.585 s, 452 kB/s
When synchronized data transfer is done to sdi and sdg in a small block
size everything works out as it should, but takes a long time.
# dd if=/dev/zero of=/dev/sdg bs=1024 oflag=dsync
56897100+0 records in
56897100+0 records out
58262630400 bytes (58 GB, 54 GiB) copied, 74235.8 s, 785 kB/s
[...]
dd: error writing '/dev/sdg': No space left on device
488386585+0 records in
488386584+0 records out
500107862016 bytes (500 GB, 466 GiB) copied, 702184 s, 712 kB/s
I have been unable to catch this kind of error leading to a crash.
The shutdown of the test computer did show the same kind of errors as
the below log. It couldn't write asynchronous data.
Best regards,
Patrik

Without more information it's impossible to tell what's really going
wrong. The logs by themselves just aren't good enough.
Messing around with the timings isn't going to fix the real problem,
which is that you keep getting write errors. Once a write error has
occurred you're already in trouble; failing to reinitialize the drive
afterward is minor in comparison.
The best thing for you to do at this point is collect a usbmon trace
showing some errors as they occur. Information on how to use usbmon is
in the kernel source file Documentation/usb/usbmon.rst.
