Hello, using 2.4.0-test9-pre2 and thinking that there are no major bugs
I found this again, I have observed what I think it's the same bug since
2.4.0-test7.

All the traces end up in stext_lock, so I think it' the same bug, this
time it happened when I was about to use the iomega parport zip with
autofs.

The modprobe of ppa failed but it was inserted (???) because of the
rename of sd.o back again to sd_mod.o

ksymoops 2.3.4 on i586 2.4.0-test9-pre2. Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.0-test9-pre2/ (default)
     -m /boot/System.map-2.4.0-test9-pre2 (specified)
