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):
Steps to Reproduce:
1. build and install swsusp enabled kernel
2. echo 4 >> /proc/acpi/sleep
Does echo 3 have any better luck?
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
swsusp isn't enabled in our builds for precisely reasons like this, it just
isn't ready for production.
