I tried to clean up my modules list from all the stuff SuSE loaded on boot:
rmmod dm_snapshot ohci_hcd snd_intel8x0 ide_cd ehci_hcd floppy ip6table_mangle
iptable_nat iptable_mangle snd_seq snd_seq_device snd_pcm_oss edd
Result was this:
Result of uname -a
Linux siso-rl-i34d 2.6.18-rc6 #38 SMP Tue Sep 5 16:14:22 CEST 2006 i686 i686

[ INFO: hard-safe -> hard-unsafe lock order detected ]
------------------------------------------------------
rmmod/5158 [HC0[0]:SC0[0]:HE0:SE1] is trying to acquire:
(proc_subdir_lock){--..}, at: [<c10811fe>] remove_proc_entry+0x40/0x18b
and this task is already holding:
(ide_lock){++..}, at: [<c115e0c1>] ide_unregister_subdriver+0x38/0xc7
which would create a new lock dependency:
(ide_lock){++..} -> (proc_subdir_lock){--..}
but this new dependency connects a hard-irq-safe lock:
(ide_lock){++..}
... which became hard-irq-safe at:

[<c120672f>] _spin_lock_irqsave+0x22/0x32

[<c1004dab>] do_IRQ+0x9e/0xbf
to a hard-irq-unsafe lock:

... which became hard-irq-unsafe at:
