Subject: Re: HPET regression in 2.6.26 versus 2.6.25 -- experimental revert for 2.6.27 failed
Date: Tue, 12 Aug 2008 18:17:15 -0700 (PDT) [thread overview]
Message-ID: <305173.54014.qm@web82101.mail.mud.yahoo.com> (raw)
> can you post /proc/iomem?
Gladly.
I wasn't sure which kernel you would like me to use, so I chose a
sample of 3:
1. linux-2.6.25 (from git) just before the commit causing the lockups
2. linux-2.6.26 (with "hpet=disabled")
3. Debian stock 2.6.26 ("linux-image-2.6.26-1-amd64", also with HPET
disabled)
Using 2.6.25 at the commit before the one that caused lockups:
