Subject: 2.6.37-rc5, pata_atiixp, DVD-ROM: kernel log flooded with "rpm_resume flags 0x4", "rpm_resume returns 1"
Date: Sat, 11 Dec 2010 17:32:34 +0100 [thread overview]
Message-ID: <20101211173234.77617d3a@stein> (raw)
Hi,
I just booted from 2.6.36 (without PM debugging configured) into
2.6.37-rc5 (with PM debugging enabled). There is endless log spam like
this:

Why is rpm_resume performed 6 times every two seconds?
host6 is pata_atiixp with an:
