Date: Tue, 14 Apr 2009 12:21:43 +0200 (CEST) From: Bart <mmx@....pl> To: linux-kernel@...r.kernel.org Subject: Oops 2.6.29.1 It happened 3 times. Every time after running amtapetype. It seems that amtapetype is stressing the system enought to make it crash. It does not happen every time. I do not know if it is related to scsi or something else so I am posting here.
