Description info 2007-05-14 15:41:23 UTC
Description of problem:

pm-hibernate gives a message about shrinking memory, then "shutting down 
console(s)", and then nothing more. pm-suspend just gives a blank screen, but 
power stays on. In both cases I can't wake up the machine, I have to hard 
reset, and it goes through the full boot (starting services etc). It worked 
with previous kernel versions.

Version-Release number of selected component (if applicable):

but no problem in kernel-2.6.20-1.2933.fc6

How reproducible:


Steps to Reproduce:
1. pm-hibernate or pm-suspend
Actual results:

Hibernate stops at "shutting down console(s)"

Expected results:

It should continue with saving to disk, stop the HD and shut down power. This 
works fine in the earlier kernel-2.6.20-1.2933.fc6

Additional info:

I can't see anything relevant in dmesg or /var/log/messages, the messages 
there are all about the boot process, not the shutdown.

The Laptop is a
Fujitsu-Siemens Amilo A1650G
AMD64 processor, 1GB memory

Comment 1 Nigel Cunningham 2007-06-12 11:12:44 UTC
Between 2933 and 2948, support for tickless kernel was added. It's not the only
thing, but I'd consider it a possibility. Would you please try booting with
nohz=off on the kernel command line?

Comment 2 info 2007-06-12 19:44:48 UTC
Yes, with nohz=off it works as it should (testing with 2.6.20-1.2952.fc6).

For your info, suspend and hibernate also work again in FC7 
(2.6.21-1.3194.fc7) without the nohz=off option (it doesn't wake up from 
suspend though, but that's a different matter).

Comment 3 Nigel Cunningham 2007-07-03 01:59:17 UTC
Ok. I'll close this as fixed in the current release then. Please feel free to
open another bug for the other issue (if you haven't already).
