Hi,

I'm getting random kernel panics (sometimes a couple times a day, sometimes it's fine for weeks) starting with the message "error running install command for acpi_cpufreq".

I'm running Ubuntu 12.10 on a Samsung NP900X3C.

The grub entry is:
Code:
recordfail
gfxmode $linux_gfx_mode
insmod gzio
insmod part_msdos
insmod ext2
set root='hd0,msdos1'
if [ x$feature_platform_search_hint = xy ]; then
  search --no-floppy --fs-uuid --set=root --hint-bios=hd0,msdos1 --hint-efi=hd0,msdos1 --hint-baremetal=ahci0,msdos1  566f6173-5216-423a-8391-86bd30cd2ad7
else
  search --no-floppy --fs-uuid --set=root 566f6173-5216-423a-8391-86bd30cd2ad7
fi
linux   /boot/vmlinuz-3.5.0-28-generic root=UUID=566f6173-5216-423a-8391-86bd30cd2ad7 ro   quiet splash $vt_handoff i915.i915_enable_rc6=1 i915.i915_enable_fbc=1 i915.lvds_downclock=1
initrd   /boot/initrd.img-3.5.0-28-generic


Has anyone had this problem? And any advise?

Thanks!

Cpufreq is bad anyway!
Install the 3.10 kernel instead. It has a new Intel CPU driver that replaces cpufreq. You will get two hours more battery life ;)

Here is how to install the 3.10 kernel: http://howtoubuntu.org/how-to-install-l ... mKwJN8hFk9
