Segmentation fault
In syslog, there is another "psaux.o: init_module: Device or resource busy"
right before the oops. strace shows that cat segfaults in the call to open
/dev/psaux .
Everything works fine (ie, no oops, mouse functions) when with the mouse
attached. I searched the archives and didn't find any other report of this
problem, so I assume this is not expected behavior. I understand that ps2
mice are finicky, but I hope something better than an oops can be achieved.
I first noticed this problem on 2.0.36ac15. I am now running 2.0.37pre12
and the problem persists. I compiled the kernel with gcc 2.7.2.3. If
anyone wants to look at my .config, it's at
http://pimlott.ne.mediaone.net/~andrew/config.oops .
Please let me know if there's anything else I can do to help.
Thanks,
Andrew
