Kernel from "ppa:kernel-ppa/ppa", I do not know how to link this bug to that ppa.

cat /proc/version
Linux version 2.6.35-14-generic-pae (buildd@hassium) (gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5) ) #20~lucid2-Ubuntu SMP Sun Aug 8 01:11:23 UTC 2010

Affecting the kernel.

Declining the Maverick specific nomination for now and leaving this open against the actively developed Ubuntu kernel (which happens to be Maverick at this time). Will re-open the nomination should a fix be narrowed down which we can confirm specifically resolves this issue in Maverick.

[Samir (samir-i)]

Using ppa kernel 2.6.35-21-generic x86_64 against 10.04.1, this bug still occurs, possibly killing wake from standby (wake fails back to startup-login screen instead of restoring previous gnome session).

there is a fix now at

[Leann Ogasawara (leannogasawara)]

Looks like the patches noted in the upstream bug report should resolve this issue. They appear to be making their way into the upstream 2.6.35.y stable kernel. They'll automatically get pulled into the Maverick kernel as a SRU (stable release update) when we sync up with the upstream stable version which contains the patches.

Fixed by commit d900329e20f4476db6461752accebcf7935a8055 .

[Iustinian T. (iustinian)]

2.6.36 from mainline kernels doesn't exhibit this bug, the stock maverick kernel does.

Is there an ETA on this fix?

This has been corrected upstream, as well as in the Maverick, and Natty series
