A bug i had with kernel version 2.4.0-test9 is still there, but there are
additional information:
When parport_pc is compiled as module, and not already loaded
"modprobe imm" yields the LOCKUP message (subject).
The iomega-drive is usable after the modprobe and despite of
the lockup.
If parport_pc is compiled into the kernel, or the modules is already
loaded, this lockup doen not happen.
the trace looks like this:
0: ?? (assume spin_lock_irqsave in blk_get_queue but printed EIP seems to
be sensless - area with no code according to the map file)
1: ll_rw_blk.c: 874
generic_make_request -> "after line q = blk_get_queue(...)"
2: ll_rw_blk.c: 925 ll_rw_block
3: ll_rw_blk.c: 287 writeout_one_page
4: filemap.c: 332 do_buffer_fdatasync
5: filemap.c: 352 generic_buffer_fdatasync
5.1: filemap.c: 278 writeout_one_page
this is on the stack trace, but maybe only since its adress is used in
call (5)
6: ext2/fsync.c: 140 ext2_sync_file
7: fs/buffer.c: 370 sys_fsync
Please CC me, if you have some comments, ideas, and thanks for your time.
