Description yuval aviel 2005-06-07 08:38:11 UTC

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (compatible; Konqueror/3.3; Linux 2.6.11-1.14_FC3.root_cubbi1_swsusp2; X11; i686; en_US, he) (KHTML, like Gecko)

Description of problem:
In an attempt to test hibernation in FC4,  
I installed the latest kernel-2.6.11-1.1369_FC4.src.rpm and enabled *only* the 
software suspend option. 
 
after building and installing the new kernel, I started the hibernation 
process with "echo 4 >> /proc/acpi/sleep". This used to work in FC1 and 2. 
Here it report a kernel BUG and hangs. 
Due to the freezing, I cant save the output. 
 

Version-Release number of selected component (if applicable):
kernel-2.6.11-1.1369_FC4

How reproducible:
Always

Steps to Reproduce:
1. build and install swsusp enabled kernel 
2. echo 4 >> /proc/acpi/sleep 
3.

Does echo 3 have any better luck?

Comment 2 yuval aviel 2005-06-07 10:13:08 UTC

Forgot to mention: The machine is HP nx9000 (Laptop). 
On this machine suspend to RAM (sleep mode 3) never worked. I.e. it never 
succeeded to fully resume. I think it got to do with the BIOS, but i'm not 
sure.

swsusp isn't enabled in our builds for precisely reasons like this, it just
isn't ready for production.
