Subject: p4_clockmod broken in 2.6.16-rc? kernels
Date: Thu, 09 Mar 2006 07:11:48 +0100 [thread overview]
Message-ID: <1141884708.7865.16.camel@homer> (raw)
Greetings,
As subject says, it appears to be broken for at least one single P4 HT
system, namely mine. 2.6.15 works fine.
With a UP compiled kernel, it fails completely, due to CPU0 failure to
initialize. With an SMP compiled kernel, CPU0 fails, but the sibling
initializes. Nothing good happens afterward though. See debug
(cpufreq.debug=7) output below.
Cheers,
-Mike
