usb problems - machine reboots

[Torfinn Ingolfsen]

Hello,

I'm not certain where I should report this, so I'll ask for comments on
this list.
I have a machine which runs FreeBSD, and when I use USB mass storage
devices on it, and copy more than a few files to them, it fails, and
quite soon after that the machine reboots. No crash dumps found.
Details:
root at kg-quiet# uname -a
FreeBSD kg-quiet.kg4.no 6.0-STABLE FreeBSD 6.0-STABLE #0: Thu Dec  8
00:56:05 CET 2005     root at kg-quiet.kg4.no:/usr/obj/usr/src/sys/QUIET 
amd64

Please note that the machine runs FreeBSD/amd64. I do not know if this
has anything to do with the problem.

The usb controllers are ohci (from dmesg):
ohci0: <OHCI (generic) USB controller> mem 0xfe02d000-0xfe02dfff irq 19
at device 19.0 on pci0 ohci0: [GIANT-LOCKED]

I have tested with several devices, here is one example:
Dec 21 16:45:00 kg-quiet kernel: umass0: CREATIVE Zen Nano Plus, rev
2.00/11.03, addr 2
Dec 21 16:45:01 kg-quiet kernel: da0 at umass-sim0
bus 0 target 0 lun 0
Dec 21 16:45:01 kg-quiet kernel: da0: <CREATIVE Zen
Nano Plus 1103> Removable Direct Access SCSI- 4 device 
Dec 21 16:45:01 kg-quiet kernel: da0: 40.000MB/s transfers
Dec 21 16:45:01 kg-quiet kernel: da0: 999MB (511936 2048 byte sectors:
64H 32S/T 249C)

(Note: I have tested this device extensively on another machine, a
ThinkPad T41 which have uhci controllers, and it works there. I can
copy all day if I want, the device just works.)

I can mount the device with no problems at all (using 'mount -t msdos
/dev/da0s1 /mnt').
I ca also copy a few files off it, or copy a few files to it. Sorry, I
don't know how many files "a few" are exactly.
But when I started copying files to the device, it got to about 60 or 70
files before it failed. When it failed, I got these in
/var/log/messages:
Dec 21 16:47:46 kg-quiet kernel: umass0: BBB bulk-out clear stall
failed, IOERROR
Dec 21 16:47:49 kg-quiet kernel: umass0: BBB reset

Dec 21 16:47:55 kg-quiet kernel: umass0: BBB bulk-out
clear stall failed, IOERROR

edited dmesg log attached.
after it failed, I aborted the copy operation, and started to copy
/var/log/messages  to another file. Suddenly, the machine rebootet on
its own. No warnings, no panics, no nothing. When it booted again, I
paid attetntion to see if it would find any crashdumps, but it didn't.

The machine runs fine except for this usb related problem, and have done
so since about FreeBSD 5.4. The mainboard in use is a MSI RS480M2-IL
(aka MS-7093). I haven't installed FreeBSD/i386 on it, so I can't test
to see if that makes a difference.

How do I debug this more?
I should probably send-pr this also, but it would be good to know more
about the real problem, so I can send the report to the right place.
