Hi,
[1. ] copy data from USB flash drive hungs-up the PC or router
[2.] If user copy data from USB flash drive CPU load is going to 100% by kernel.

It is OK if you don't like to work with this router.
But, If you try to work with some software in user space you will be
disappointed. Kernel doesn't free CPU for user space at all.
CPU is fully occupied by URB kernel mechanism.

It seems like power of 1 core is occupied by URB mechanism.

1 core router:

[6.] A small shell script or example program which triggers the
- sar -P 1 100 in another console
- execute cat /dev/sda > /dev/null in one terminal

Kernel driver in use: r8169
[7.6.] SCSI information (from /proc/scsi/scsi)
no such file
[7.7.] Other information that might be relevant to the problem
It seems that kernel URB mechanism took a lot of CPU performance as
iowait and in spin-locks.
As you see above the problem exist for new kernel too. Problem was
found on a router when I tried to copy data from connected USB flash
via Samba.
For testing I used cat /dev/sda > /dev/null to avoid influence from file system.
My suggestion is not decrease CPU Load but free a piece of CPU for user space.
This fix is important for routers and PC which has only one core and
USB handling is not main task.
[X.] Other notes, patches, fixes, workarounds:
Fix which helps to free CPU for user space if it is needed was made:
drivers/usb/core/message.c
void usb_sg_wait (struct usb_sg_request *io)
{
.......
for (i = 0; i < entries && !io->status; i++) {
.....
switch (retval) {
.....
case 0:
cpu_relax();
yield (); // FIX
break;
....
It helps to decrease USB speed if user space software needs CPU but in
this case USB speed in idle CPU (no user space software is executed)
is decreased only less than 5%.
Copying the file via Samba from USB connected to the router router
(graph from Slurm)
-----------------------------------
Without fix

USB speed:

software copy USB data

CPU is overloaded by 100% kernel usage. User space software is working
as turtle, cannot start properly.
USB speed is not decreased when user space software is executed (graph
above). User is

As we see, CPU is freed for user space and USB speed is decreased
(graph above) if it is needed.
So, user space is working as without any USB coping. User is CPU is
divided between user space and kernel.

2.6.8 is a very ancient kernel.
Please either try to reproduce it with a vanilla ftp.kernel.org 2.6.15
or contact your vendor (Debian?) regarding this issue.

(i'm not subscribed to linux kernel mail list)
System dying while watching video from cdrom.
When I installed kernel 2.4.18, anytime i was watching video from cdrom
system was dying in 10-15 minits and hdd led was on
(normally hdd led do not light while reading from cdrom).
There is no such problem in 2.4.17.

wandering if it is hardware or software problem?
