Description:
The second core dies when resuming from suspend. It is not possible to get it back without rebooting. It was stated that forcing removal of "acpi_cpufreq" module just before the final steps of suspend could bypass the problem. But Arch's kernel has the kernel's option unset: [*] Enable loadable module support ---> [*] Module unloading [ ] Forced module unloading http://bbs.archlinux.org/viewtopic.php?pid=339852 http://gnugeneration.epfl.ch/users/fasnacht/d630_cpufreq Could this option be enabled? Thank you Additional info: * package version(s) kernel26 2.6.24.3-3 * config and/or log files etc. Steps to reproduce: |

but "# CONFIG_MODULE_FORCE_UNLOAD is not set"
Are you saying instead that the problem about second core dying could be fixed? I can't afford my computer to not boot, so I want to be sure before trying to change the kernel.
Thanx
Sorry I forgot to say I am on x86_64.
However, it is only used if explicitly specified in rmmod/modprobe, so there should be no harm. I think we can add it. Tobias, what do you think?
My cpufreq is really messed up as in bug #10106, so it is hard to investigate... Force module unloading is a first step, and cpufreq debug is another.
