Bug Description

When resuming from hibernation the last thing that's written is "Mounting root file system" (the "OK" is not written). Then usplash quits and I have a blank text mode screen with the cursor blinking in the top left corner. No system activity from then on.

My kernel is:
Linux lt-mf 2.6.17-6-686 #2 SMP Fri Aug 11 22:09:15 UTC 2006 i686 GNU/Linux

I have not tried any other kernels, but hibernation worked in dapper.

Suspend-to-RAM works well.

dmesg output attached.

When attempting this, let the system sit for as much as 5 minutes to see if it ever gets anything further.

I've now let it sit for over 10 minutes with no change. So it's really stuck.

Isn't there a way to enable some debugging output?

Remove the "quiet splash" options from the kernel command line using
grub's menu editor (ESC when grub comes up on boot).

OK, I did that and - surprisingly - the machine resumed normally. I tried all combinations and the result is that the splash option breaks resume for me.

So it seems the new high-res usplash is at least the trigger if not the culprit here...

I have seen the same resume failure on my T42. I hadn't tried resuming without usplash, but will test that shortly.

Confirmed, disabling usplash fixes resume for me as well

This ought to fix it. Awkward race - the kernel VT switching interacts really badly with attempting to freeze processes. Let's just avoid the issue.
