From bcdcd8e725b923ad7c0de809680d5d5658a7bf8c Mon Sep 17 00:00:00 2001 From: Pavel Emelianov Date: Tue, 17 Jul 2007 04:03:42 -0700 Subject: Report that kernel is tainted if there was an OOPS If the kernel OOPSed or BUGed then it probably should be considered as tainted. Thus, all subsequent OOPSes and SysRq dumps will report the tainted kernel. This saves a lot of time explaining oddities in the calltraces.
