[Bug 410726] New: 2nd CPU core is disabled after suspend to ram
https://bugzilla.novell.com/show_bug.cgi?id=410726 Summary: 2nd CPU core is disabled after suspend to ram Product: openSUSE 11.0 Version: Final Platform: i386 OS/Version: openSUSE 11.0 Status: NEW Severity: Normal Priority: P5 - None Component: Kernel AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: dgege1@hotmail.com QAContact: qa@suse.de Found By: Customer When I suspend to ram my laptop and then resume it, KPowersave tells me that the 2nd processor is deactivated. I have no idea if that's true or if KPowersave is screwed up. My system is a Dell XPS M1330. I'll give out any requested info. -- 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.

A quick and ugly workaround is to force the removal of acpi_cpufreq and reloading it when suspending to ram. I hope this gets fixed eventually. -- 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.

So, as far as I can see, these are separate issues. I did find this that bug #349802 which seems the same, but for 10.3. -- 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.

ok, after doing some testing and checking online, this seems to be a known problem Could you point to the most interesting discussion, pls.
From dmesg after suspend, it looks like we have a corrupted or wrong DSDT
This seem to get an interesting problem. table: ------------------------------- Intel machine check architecture supported. Intel machine check reporting enabled on CPU#1.

For me it looks like a very small part of the BIOS DSDT/SSDT table is broken. This small part only gets evaluated/parsed after suspend. Found unknown opcode 23, 17, 20 could help to find the corrupted place. Unfortunately the extracted DSDT.dat ends in an endless loop when running: acpiexec DSDT.dat Therefore this cannot be that easily debugged in userspace.
