While doing insert/remove (quickly) tests on USB,
I managed to trigger an Oops on 2.6.23.8 on a call
to strlen() in make_class_name().
Does this oops occur under 2.6.24? The SCSI async scanning code was
changed between 2.6.23 and 2.6.24, in a way intended to prevent exactly
this sort of thing.
And below is a "prevented Oops", courtesy of the patch.
The next bug to fix is whereever the code resides that
repeatedly continues to flog the unplugged device
after the test, despite SCSI returning host_byte=DID_NO_CONNECT.
It has probably already been fixed.
Besides, it's not the flogging an unplugged device that causes the
oops. It's trying to unregister a device that was never registered in
the first place.

Well, duh, I kinda knew that already, thanks. ;)
But the flogging continues multiple times per second
until the system is shutdown, so it is "the next bug to fix".
Unless the 2.6.24 code already has that one taken care of.
This machine doesn't run 2.6.24 (yet) due to other incompatibilities.
Cheers
