Linux crash when using FTDI FT232R USB to serial converter on AMD boards.

Linux crash when using FTDI FT232R USB to serial converter on AMD boards.

[StarostaCZ@gmail.com]

Hello all,
we are development and manufacturing company that use your FT232R serial 
converter for couple of years with our software. We consume about a 
hundreds pcs of FT232R per yer. We use FT232R as USB serial converter 
with direct access (no virtual serial port) and as a "hardware key" 
using FTDIChip-ID. We operate our software with FT232R converters on 
Windows and Debian Linux operating system.

We have used Intel motherboards with Intel processors so far. We want to 
use AMD motherboards with AMD processors too. *We made a couple of tests 
on AMD motherboards with AMD processors and Debian Linux 9.6, but we 
have come across a big problem.
**When we open internal EEPROM of FT232R for reading, there will arise 
many error messages in system log files. And then Debian Linux crash 
after some time!*


_1) Hardware configurations:_
- motherboards with AMD A320M chipset:
   - MSI A320M PRO-VD PLUS, 
https://www.msi.com/Motherboard/support/A320M-PRO-VD-PLUS
   - ASUS PRIME A320M-K, https://www.asus.com/Motherboards/PRIME-A320M-K
   - GIGABYTE A320M-S2H, 
https://www.gigabyte.com/Motherboard/GA-A320M-S2H-rev-1x#kf
- latest bios installed, default bios configuration loaded,
- CPU AMD Athlon 200GE, AMD Ryzen 3 2200G
- 4GB RAM, SSD drive Kingston A400 120GB

_2a) Operating system A:_
- Debian Linux 9.6 64bit, https://www.debian.org/distrib/, 
https://cdimage.debian.org/debian-cd/current/amd64/iso-cd/debian-9.6.0-amd64-netinst.iso
- installed from Netinst installer WITHOUT graphic dekstop, default 
configuration
- tested kernels
   - default kernel 4.9.0.8-amd64, 
https://packages.debian.org/stretch/linux-image-4.9.0-8-amd64
   - backports kernel 4.18.0-0.bpo.1-amd64, 
https://packages.debian.org/stretch-backports/linux-image-4.18.0-0.bpo.1-amd64

_2b) Operating system B:_
- Ubuntu server 19.04 64bit, http://releases.ubuntu.com/19.04/, 
http://releases.ubuntu.com/19.04/ubuntu-19.04-live-server-amd64.iso
- installed WITHOUT graphic dekstop, default configuration
- tested kernels
   - default kernel 5.0.0-amd64, 
https://packages.debian.org/stretch/linux-image-4.9.0-8-amd64
   - experimental kernel 5.0.9-050009-generic amd64, 
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.0.9/

_3) Drivers_
- libftd2xx drivers version 1.4.8, https://www.ftdichip.com/Drivers/D2XX.htm

_4) Performed tests_
You can repeat this test:
- connect FT232R into USB2.0 port (not USB3 port!)
- use examples in directory: ...\libftd2xx-i386-1.4.8.tar\release\examples\
- add parameter "-m32" to "CFLAGS" variable into "Rules.make" file
- compiled "\examples\EEPROM\user\read\"
- run script "test.sh" - see attached file
- *Debian Linux or Ubuntu server crashes after some minutes* - see 
attached kernel logs from our system
- see "kern.log" https://paste.ee/p/xxIZ2


_5) Very important note_
*This problem occurs when FT232R is connected into USB2.0 port only!*
When it is connected into USB3 port, all works fine, no error messages, 
no crash.

_6) Other test that we made_
- we made other tests on Windows 10
   - same configuration with ASUS PRIME A320M-K motherboard
   - latest drivers + latest FTDI drivers
   - FT232R connected to USB2.0 or USB3 - no problem

- we made the same tests on Intel architecture (that we use now)
   - motherboard MSI B250M PRO-VH, CPU Intel Pentium G4560, 4GB RAM, SSD 
drive Kingston A400 120GB
   - same operating system Debian Linux 9.6 64bit as descripted above
   - FT232R connected to USB2.0 or USB3 - no problem

So this is a debian 4.18 kernel seemingly crashing due to a xhci or
iommu issue.

Can you reproduce this on a mainline kernel?

If so, please post the corresponding logs to the lists and CC the xhci
and iommu maintainers (added to CC).

Hello,
sorry for other questions, but I am new in this list:
Is Ubuntu server 19.04 with "kernel 5.0.9-050009-generic" good for this 
test?
Can I add attachments to this lists?
And who is xhci and iommu maintainers? Are they CC in this mail?

Yes, that might do depending on what else debian put in that kernel.

Sure, it's even preferred. Just try to trim non-relevant bits, and
perhaps provide a link to the full log.

> And who is xhci and iommu maintainers? Are they CC in this mail?

Yes, that's Mathias and Joerg, respectively, that I added on CC.

Re: Linux crash when using FTDI FT232R USB to serial converter on AMD boards.

[StarostaCZ@gmail.com]

[-- Attachment #1: Type: text/plain, Size: 6871 bytes --]

Ok,
I attach log from today test on Ubuntu 19.04 with5.0.9-050009-generickernel.
Full kern.log: https://paste.ee/p/yF3Qi#section0
Dmesg log: https://paste.ee/p/yF3Qi#section1

Summary:
- motherboard with AMD A320M chipset, CPU AMD Athlon 200GE
- Ubuntu 19.04 default instalation, kernel 5.0.9-050009-generic
- connected "FTDI FT232R" (USB to serial converter) to USB port, latest 
FTDI libftd2xx drivers version 1.4.8 installed, 
https://www.ftdichip.com/Drivers/D2XX.htm
- ftdi_sio driver is unloaded (rmmod ftdi_sio)
- problem is with reading EEPROM content from FTDI FT232R chip
- problem is on USB2.0 port only, on USB3 port it works fine

Ok,
I attach log from today test on Ubuntu 19.04 with5.0.9-050009-generickernel.
Full kern.log: https://paste.ee/p/yF3Qi#section0
Dmesg log: https://paste.ee/p/yF3Qi#section1

Summary:
- motherboard with AMD A320M chipset, CPU AMD Athlon 200GE
- Ubuntu 19.04 default instalation, kernel 5.0.9-050009-generic
- connected "FTDI FT232R" (USB to serial converter) to USB port, latest 
FTDI libftd2xx drivers version 1.4.8 installed, 
https://www.ftdichip.com/Drivers/D2XX.htm
- ftdi_sio driver is unloaded (rmmod ftdi_sio)
- problem is with reading EEPROM content from FTDI FT232R chip
- problem is on USB2.0 port only, on USB3 port it works fine

Ok,
I attach log from today test on Ubuntu 19.04 with5.0.9-050009-generickernel.
Full kern.log: https://paste.ee/p/yF3Qi#section0
Dmesg log: https://paste.ee/p/yF3Qi#section1

Summary:
- motherboard with AMD A320M chipset, CPU AMD Athlon 200GE
- Ubuntu 19.04 default instalation, kernel 5.0.9-050009-generic
- connected "FTDI FT232R" (USB to serial converter) to USB port, latest 
FTDI libftd2xx drivers version 1.4.8 installed, 
https://www.ftdichip.com/Drivers/D2XX.htm
- ftdi_sio driver is unloaded (rmmod ftdi_sio)
- problem is with reading EEPROM content from FTDI FT232R chip
- problem is on USB2.0 port only, on USB3 port it works fine

New test on kernel Linux version 5.1.0-050100-generic. Same problem, 
system crash after a few seconds.
Full kern.log: https://paste.ee/p/EmLsw
I can do access to my pc through SSH if useful.

Your first step would be t verify whether your kernel has the
fix coming in the patch Joerg mentioned.

Re: Linux crash when using FTDI FT232R USB to serial converter on AMD boards.

As I wrote, I made new test on kernel Linux version 5.1.0-050100-generic 
amd64:
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.1/
Same problem, system crash after a few seconds. Full kern.log: 
https://paste.ee/p/EmLsw

Unfortunately, I can't judge if the patch is there, but I found, that 
this patch was added to kernel 5.0.2:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/iommu/amd_iommu.c?id=4e50ce03976fbc8ae995a000c4b10c737467beaa
Can I somehow verify that the patch is in this ubuntu kernel 5.1.0?

Most helpful. First, try to replicate this with the iommu disabled.
Secondly, make a proper bugreport mentioning the affected kernel version (5.1)
Thirdly, if possible replicate this with the vanilla kernel from kernel.org

You would need to look into the kernel source, but this is not necessary.
Joerg's guess was incorrect.

I am afraid, that is not possible. My skills is not too good - is there 
some procedure to how do this?
I made test with mainline kernel 5.1.2 from 
https://kernel.ubuntu.com/~kernel-ppa/mainline/
but computer crash on boot (kernel panic: unable to mount root fs...).

1. Determine whether the bug depends on the use of an IOMMU
2.Send a new report to the corresponding mailing list

Your initrd has most likely not included a driver for the filesystem on
your root device.

3. include the log with iommu disabled and mention that you disabled

You will be asked whether this worked in earlier version of the
