SubjectRe: a couple of USB related Oopses
OK, after some compilation problems with 2.5.6-pre2 (ide-scsi wouldn't
compile, then OSS sound had an error too.. both not essential to me), I
got it up, and still got a panic. It's attached. Should I try the other
UHCI driver now?

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/ (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.

No modules in ksyms, skipping objects
Warning (read_lsmod): no symbols in lsmod, is /proc/modules a valid lsmod file?
