evdev_disconnect+0x65/0x9e [evdev] SS:ESP 0068:c1967e68
I'm using Debian stable/testing/unstable with homemade kernel 2.6.23.12
(patched with tuxonice-3.0-rc3-for-2.6.23.9).
I tried to get my Wacom Bamboo grafic tablet to work with linux and the
xorg driver from linuxwacom-0.7.9-4 (http://linuxwacom.sourceforge.net/).
After 'configure/make/make install' from source and configuring Xorg, I
got the tablet working for a simple user. But each time I tried to login
with X as root (I know .... Bad idea .... :-)) xserver got restarted.
I tried to strace gdm via an ssh session from a second computer. Because
I tried to follow the forks, I had to kill strace after forcing the
restart. Some time after the 'kill', while examining the trace files, I
recognised the Oops in the window with the ssh session on the second
computer. The traced system was still up and running with X.
At the top of the log extract, you can see USB disconnect messages,
perhaps leading to the Oops. That's strange because I haven't
disconnected any USB device.
Not only the tablet got disconneced. It was connected to the computer
via an USB hub (Belkin), which has been disconnected too.
The USB system seemed to be a wreck at the moment after the Oops. lsusb
and usbview didn't work (no output for about a minute, had to be
killed). But keyboard and trackball were still working.
I haven't been able to reproduce the problem but perhaps somone has seen
a similar problem. I providing the output of 'lspci -v' and 'lsusb -v'
at the end of this mail.
Regards,
Berthold
