I've not upgraded to this kernel yet, waiting for it to go into core. But is it infact working other than this issue? On Tue, Mar 20, 2012 at 5:08 PM, Genes MailLists wrote:

linux 3.3 from testing - fully updated from test repo.

I had plugged my cell phone in to usb - a few times in and out. After unplugging, I closed laptop lid - the sleep light which normally flashes then goes steady to indicate laptop is sleeping did not. I opened lid - and found khubd process at 100% cpu.

In earlier kernels there were some problems with usb if I attempted to sleep a laptop with a USB device plugged in - but i thought there were some fixes to this problem.

Anyway - this is what got recorded in system log:

Where is the preferred place to report this?

thanks!

There is also a known problem with btrfs (where your fs sometimes appears to be out of space, even though it is not).

There is also a reported issue with ASPM - I seem not to have a problem even tho lspci -vvv | egrep ASPM shows it enabled for me. https://lkml.org/lkml/2012/3/19/227 gene

I filed a bugzilla here: https://bugzilla.kernel.org/show_bug.cgi?id=42975 gene/

To add to this - I get an oops on shutdown as well. Fresh boot and sleep/shutdown is not a problem. It seems to need aging and oddly happens only at work (so far). Work has 802.11 wifi (not N) and a different Bluetooth mouse - and I occasionally charge my cell via usb but not always ... no response to above bz.

Yes, there is some oops concerned with bluetooth at shutdown. I get so many small bugs, that we should absolutely wait for 3.3.1 before pushing any further.
