It is very true ;) To be more specific I currently have two szenarios:
The QLogic iSCSI card I have doesn’t work on CentOS, but the software
open-iscsi implementation works fine, also ocfs2 does not panic, once I
raise the heartbeat timeout to 30 (not touching the topic of really poor
performance here).

On SuSE 10.1 RC1 the QLogic card works fine, but OCFS2 panics the machine.

Would be nice to have a half-centos, half-suse system in these days …

"You are not authorized to access bug #157463." However, I use the
QLogic iSCSI card on SuSE, so I have reason to believe the bug does not
affect me. It is probably refering to the software iscsi implementation,
though I can't be sure since I can't access the bug.

Novell told me to try the very latest kernel (whatever that means these
days, 2.6.16.7 is probably quite aged), but there the qla4xxx driver
does not compile. ;(
