Oops after update to 2.4.20



Is anyone aware of problems with usb and 2.4.20? And what should I do with
Oops messages?

I upgraded to 2.4.20.  I used kernel source with XFS support from SGI via
cvs.

I was upgrading from 2.4.18 to fix the problem of kernel modules having
the wrong "used" count (visor modules not unloading).  It fixed that
problem.

Now after a few hotsync attempts which loads visor and usbserial I get an
oops and the machine becomes unstable, Oops'ing quite often until the
machine hangs.

It's happend quit a few times since the upgrade.

One message I see is:

Dec 29 23:28:58 bumby kernel:  <1>Unable to handle kernel paging request  
at virtual address e5b2f470

Another:

Dec 29 23:19:10 bumby kernel: Unable to handle kernel NULL pointer
dereference at virtual address 00000013

And here's a full Oops.
