I hope to have reached the correct addresses... :-/
This is a modified SuSE 7.0 box, with the 2.4.17-rc1 kernel +
the following patches:
LVM 1.0.1 (the L)
linux-2.4.11-VFS-lock.patch (the V)
and LVM_VFS_ENHANCEMENT enabled in drivers/md/lvm.c
(the X)
(which basically allows exploiting the usage of the
linux-2.4.11-VFS-lock.patch to mount online snapshots
of journalled file systems.)
Current-Linux ls a softlink to the correct linux sources, set
via uname during the boot process.
The machine is a Dual-Celeron SMP machine on the ABIT BP-6
board.
jpilot is a 'palm pilot' connection program (and more), a
Handspring Visor (a palm-clone) was syncing via it's USB
connection as the oops happened. The logfiles say that ISDN
had disconnected almost exactly a minute before the oops, so
it was offline.
The kernel keeps chugging on, luckily.
The oops:

There is a known bug in the visor driver that can happen when the visor
is done syncing and then disconnects, while the pilot-link connection
(which is what jpilot uses) is still open. Can you load the visor
driver with "debug=1" and see if this oops still happens (and if so, can
you send me the kernel debug log?)
thanks,
