Comment 96 for bug 625364

Did any of these patches that are suspected of causing this go into the 2.6.38 branch as well?

I've just bought an SSD for my laptop and installed Kubuntu Maverick. Before I was using Mint 9 KDE, with which my hotkeys (volume, brightness, etc.) worked fine. With Maverick, even with dist-upgrade, they did not.

I then used the Ubuntu kernel PPA for Lucid to install the 2.6.38-27~lucid generic image, and all buttons work, even my touchpad is properly recognized and customizable, which is a first for Linux on this laptop.

Susend/resume, however, results in a hard lock on resume. I can usually either get a flash of the X session, or get the mouse cursor to hover over a TTY by (Ctrl+)Alt+Fx'ing around, but it's always "dead" and requires a hard shutdown. No blind-typing possible and power button does not trigger the ACPI shutdown (or how you put it) that it usually does.

I tried the latest natty version, 2.6.38-1.28, and the issue is the same. I also just re-reinstalled as I decided to use Btrfs instead of ext4, but as you'd expect that didn't change anything.

The reason I'm mentioning this last thing is because I'm currently looking at what looks like a kernel oops, and it's mentioning btrfs,

kernel BUG at /build/buildd/linux-2.6.38/fs/btrfs/disk-io.c:2344!

The fact that this is the first line after the ----[ cut here ]---- one might suggest it is IO-centric? I don't know. I'm gonna photograph the display in case anyone wants to see it :)

FTR, I opted to encrypt my home dir when installing, which also meant I have swap on cryptoloop, apparently. Don't know if this matters, just saying ;)
