Subject: regression: 100% io-wait with 2.6.24-rcX
Date: Mon, 7 Jan 2008 11:51:10 +0100 [thread overview]
Message-ID: <200801071151.11200.lists@naasa.net> (raw)
Hi,
when booting kernel 2.6.24-rc{4,5,6,7} top reports up to 100% iowait, even if
no program accesses the disc on my Thinkpad T40p. Kernel 2.6.23.12 does not
suffer from this. Is there anything I can do to find out which process or
which part of the kernel is responsible for this? I can try to bisect it, but
maybe there are other possibilities to debug this, since I cannot boot this
computer frequently. I discovered, that there is no iowait within the first
few seconds after waking up from suspend to ram...
regards,
Jörg
