Re: [Gumstix-users] Help with PM on 2.6.32 - kernel panic on suspend

[Keane, B. (STRX) <ben...@ka...>]

Hi,

It seems no one can help with this issue, but I thought I'd try one last time...

... Because I have new information...  On suspend, with debugging a few extra printk's added into the kernel, I get the following:

...
power power.0: LATE suspend
power_suspend_late return 0

Does anyone have any experience on these types of issues/bugs that could offer assistance?

Does someone know a mailing list that this type of issue might be better suited for?


Thanks in advanced,
