Subject: 2.6.21-rc7-mm2 "irqpoll" seems to be broken
Date: Thu, 26 Apr 2007 15:06:20 +0530 [thread overview]
Message-ID: <20070426093620.GB2626@in.ibm.com> (raw)
Hi,
I am booting 2.6.21-rc7-mm2 on x86_64 box with "irqpoll" command line option
and it panics. I can reproduce this problem easily on this box. Please
let me know if serial console output is required.
2.6.21-rc7 works just fine. So problem seems to be in some -mm patch.
