SubjectRe: a couple of USB related Oopses
Ah, I tried it with 2.5.6-pre2 and usb-uhci.. still got a panic, when I
tried to print to the printer (which is what I was doing before too)
Also, got these in my kernel log...

ksymoops 2.4.3 on i686 2.5.6-pre2. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.5.6-pre2/ (default)
-m /boot/System.map-2.5.6-pre2 (default)

Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.

Warning (compare_maps): ksyms_base symbol idle_cpu_R__ver_idle_cpu not found in System.map. Ignoring ksyms_base entry
Warning (compare_maps): ksyms_base symbol vmalloc_to_page_R__ver_vmalloc_to_page not found in System.map. Ignoring ksyms_base entry
