Similarly to what I reported for 2.5.3-dj1, the following big bunch of
OOPSes occur when the usb-uhci module is unloaded. Something similar
happens with uhci, but I have not tested it. Removing usb-uhci appears
to leave usbcore in such a state that modprobing usb-uhci into the
kernel again causes instant lockup. Moreover, the system runs for a few
seconds (of typing, if that's important) after these oopses before it
completely deadlocks, no SysRQ or anything. However, this last time it
didn't deadlock for over ten seconds as I alternated between Alt-SysRq-s
and Alt-SysRq-u. Looks like it's something to do with locking? I've
memtest86ed the machine and don't believe memory corruption is to blame.
Kernel patched thus: 2.5.3, -dj4, ACPI (20020207), built with gcc-2.95.4
and binutils 2.11.92.0.12.3 (from Debian Woody). There were no other
modules loaded. Anything else I can offer?
ksymoops 2.4.3 on i686 2.5.3-dj4. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.5.3-dj4/ (default)
-m /boot/System.map-2.5.3-dj4 (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.

This looks like the symptom of my driverfs patches for USB that ended up
in the -dj kernels. I don't know which version of that patch is in the
-dj kernel.
Can you let me know if 2.5.4-pre3 has this problem?
thanks,

I thought I dropped this in favour of the usb/driverfs changes in 2.5.4pre3,
it's possible I overlooked something, I'll double check later.

No, it does not have *this* problem, however...
rmmod usb-uhci
rmmod usbcore - "in use"
umount /proc/bus/usb
rmmod usbcore
modprobe usbcore
mount -t usbdevfs none /proc/bus/usb
modprobe uhci - OOPS. Didn't manage to capture it. System kept running.
rmmod uhci - "in use"
modprobe usb-uhci - two messages then deadlock except for Alt-SysRQ.
I suppose two drivers atop one another is bad and I shouldn't do that.
Booting 2.5.4-pre3 again gave me an oops in the first modprobe usb-uhci.
Here is the *really weird* decode of it:

That's the important one. Everything else was just errors because of
this one. Let me know if you can capture this.
