I'm debugging hibernate / suspend to disk on the HP nx6325 (ATI SB400 chipset), the cases below are tested with "powersave -U" from the GUI or the Hibernate trigger from the GNOME Task bar.
- without additional kernel options, it hangs on suspend early - switching to the text console, /etc/pm/hooks/50modules hangs in "modprobe -r button" -> Added a check to 50modules to skip unloading button.ko,
you could also edit /etc/pm/config:SUSPEND_MODULES :-) This might be Thomas' famous "ACPI is fscked up on HP" bug.
continued testing with this change:
- with "noapic", it resumes once from the Desktop, but 2nd hangs on suspend - with "noapic maxcpus=0" (and with unloading button.ko disabled) things do look better so far...
side note: with "maxcpus=0", without "noapic" the machine is slow in booting and hangs eventually durng boot. The same happens on the Acer Ferrari 1000, it's suspend problem is tracked in bug 228344.
Needs more testing and fixing of the issues found, for example the broken unload of button.ko. A temporary workaround for clients can be also be to list the ACPI modules to load in /etc/sysconfig/powersave/common
/etc/sysconfig/powersave is no longer used for suspend settings, pm-utils is used now.
like this:
ACPI_MODULES="ac battery processor"
Fix for rmmod button.ko during suspend wanted/needed.
edit /etc/pm/config. But if "modprobe -r button" does not work, it is a kernel problem IMO :-) -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
