We need more information than this. What USB devices and drivers are you
using? (lsusb, lsmod)

Attached to usb port is an ps2-to-usb convertor for a d-link 2 port KVM,
DKVM-2K (keyboard cable). The idea is to use the same monitor for 2
different computers - sparc/intel) and this way I can trick the KVM switch
to enable vga output.

May 28 09:44:11 mailq kernel: [ 553.669333] usb 2-1: new low speed USB device using ohci_hcd and address 2

Without kvm cable attached lsusb list the following entries:

# lsusb
Bus 004 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Output is not consistent and sometimes I only get (between reboots):
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Anyway, I only have this problem for the last 2 kernels. Everything was
working fine before. I did not had any kernel crash before (not sure
about lsusb).

Today for the first time I tried to connect a memory stick and the result
was complete blockage of the computer.

The usb board works fine on computers using intel processors.

Output for "strace -f -ff -o lsusb.log lsusb" attached. Also attached
output for dmesg.


Sincerely,
Gabriel

Wow, that's no good.

Any news? v2.6.27-rc1~946^2~45 (USB: ohci_hcd hang: submit vs. rmmod
race, 2008-07-01) or some other fix around then might have fixed this,
so I'd be interested in hearing how a squeeze or later kernel behaves.

Thanks for reporting it,
Jonathan

Well, I remove the pci card and... that's it. And, now I use kernel
2.6.32-5. I still have the usb card so I suppose I can test again with
this kernel if someone is interested. Not sure if I can do the before
January 2012.


Sincerely,
Gabriel

Yes, that would be useful. (And testing with 3.x would be useful, too;
the only package from outside squeeze that should be needed in order
to try it are initramfs-tools and linux-base.)

That's fine. Thanks for the update.

I made a quick test this morning. There are good news and bad news.

Good news:
- - the computer does not freeze, no kernel oops.
- - I can mount the usb drive.

Bad news:
- - I cannot mount the usb drive all the time.

The test was made like this:
1. Power off, insert pci card, boot.

2. Insert usb flash drive in one usb port. Flash drive recognized as
sdc(1).

3. Trying to mount /dev/sdc1 failed after a long timeout. Some
"usb 1-2: device descriptor read/64, error -60"
messages in terminal and log file.

4. Removed the usb drive, inserted in another port, flash drive not
recognized. Same kind of messages in terminal and logs.

5. Removed usb drive, inserted in previous usb port, flash drive
recognized as sdc(1). Mount successful.

6. Removed usb drive, inserted in the same usb port, flash drive not
recognized. Same kind of messages in terminal and logs.

7. Removed usb drive, inserted in the same usb port, flash drive
recognized. Mount successful.

Log file attached.


Sincerely,
Gabriel
