Instructions for building a patched kernel package are at http://kernel-handbook.alioth.debian.org/ch-common-tasks.html#s4.2.1. Ben, Thanks for the patch. I build and installed patched linux-image and after that I have not seen those syslog messages anymore. So looks like the patch fixed the issue. -- Juha -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe. Trouble? Contact listmas...@lists.debian.org

Dear Maintainer,
Recently I noticed that syslog is flooded with these kind of messages:
[...]
This is probably the result of run-time power management. It seems very
eager to turn off the USB ports, but I don't think that's actually a
problem.
I do recognise that syslog should not be filled up with this noise,
though. Can you test whether the attached patch fixes this for you?

Subject: PCI/PM/Runtime: make PCI traces quieter
commit 85b8582d7ca516030efb84d94fa29a73c1d9a125 upstream.
When the runtime PM is activated on PCI, if a device switches state
frequently (e.g. an EHCI controller with autosuspending USB devices
connected) the PCI configuration traces might be very verbose in the
kernel log. Let's guard those traces with DEBUG condition.
