Re: kernel panic (?) using USB Ethernet adaptor [axe] on OpenBSD 3.6



Hi OpenBSD gurus,

this is about as much information as I can glean from the system following the
kernel panic. The savecore is failing, so can't get a core image for you. Also
ps is too much info to copy by hand.

If you need more info, please give me instructions, and I'll see what I can get.

thanks.

> Synopsis: kernel panic using axe (USB ethernet) device
> Severity: critical
> Priority: low
> Category: OpendBSD i386
> Class: sw-bug
> Release: 3.6 Release
> Environment:
    System: OpenBSD 3.6
    Architecture: OpenBSD.i386
    Machine: i385
> Description:
Use of USB Ethernet device (axe) [Netgear FA120] causes kernel panic. Time of
occurance after boot is random. Can be between 10 seconds or up to 36 hours
after boot.
Smooth operation with usb device disconnected (using built in ethernet adaptor).

> How-To-Repeat:
----------------
Part A - installation
Have installed minimum install sets from openBSD36 release(eg no X-packages, no
additional packages)
Install process was (1) burn boot image to CD; boot from CD; (2) down extra
install sets to CD, install on target from CD.
USB Ethernet recognises by installer and configured as DHCP client.

Part B - Operation
Log in as root. run ping google.com.
Kernel panic will occur anytime from, say 10 seconds to 36 hours after booting.
(Also can crash after boot, but without root login.)

Attachments:
------------
openbsd36.dmesg          # output from dmesg
openbsd36.dmesg.boot     # /var/run/dmesg.boot
openbsd36.ifconfig       # output from ifconfig -a
openbsd.pbr              # as specified for multiboot

# can't get output from dump or savecore unfortunately. "no dump, not enough
free space on device"

Panic Message:
--------------
# this is entered here by hand, so spaces, etc, may not be correct
uvm_fault(0xd05d62a0,0x0,0,3)->c
kernel: page fault trap, code=0
Stopped at      usb_task_thread+0x65:    movl %...,0(%eax)

Trace
-----

ps

At least, please send a dmesg, and a traceback.  That way the
usb people can have a look, and possibly fix what is wrong.
