Subject: Re: Regression in TSC unstable -- confirmed
Date: Mon, 11 May 2009 02:26:48 +0200 [thread overview]
Message-ID: <200905110226.50115.elendil@planet.nl> (raw)
In-Reply-To: <alpine.DEB.2.00.0905072359530.28378@gandalf.stny.rr.com>
I'm seeing the same issue with 2.6.30-rc5 (not tested previous RCs on that
box) on a system for which TSC has always been usable.
$ dmesg | grep TSC
Fast TSC calibration using PIT
checking TSC synchronization [CPU#0 -> CPU#1]: passed.
Marking TSC unstable due to TSC halts in idle
The last line is new with 2.6.30. After reverting a71e4917dc0 the TSC
works fine again.
The system has a Intel D945GCZ mainboard with dual core Pentium D
(3.20GHz) processor running x86_64 and Debian Lenny.
Cheers,
FJP
(Thanks to Steven for doing the bisection.)
