Subject: Regression in 2.6.36-rc1 bisected to commit 9d8888c
Date: Thu, 19 Aug 2010 21:26:43 -0500 [thread overview]
Message-ID: <4C6DE7E3.4030702@lwfinger.net> (raw)
With 2.6.36-rc1 from the mainline git tree, my x86_64 system running on an AMD
Turion 64 x2 TL-60 has required pressing keys to get booting to advance. This
behavior begins as soon as the kernel is loaded. I bisected the problem to:
commit 9d8888c2a214aece2494a49e699a097c2ba9498b
Author: Hans Rosenfeld <hans.rosenfeld@amd.com>
Date: Wed Jul 28 19:09:31 2010 +0200
x86, cpu: Clean up AMD erratum 400 workaround
Remove check_c1e_idle() and use the new AMD errata checking framework
instead.

Reverting this patch allows the current 2.6.36-rc1+ to boot normally.
This problem is entered into the Kernel Bugzilla as Bug #16636.
