starting about 2 days ago ubuntu keeps crashing. I have the latest kernel installed 3.0.0-15-generic. When I say it's crashing, screen turns black and scrolls the following. (I couldn't save it so i had to type it manually hence im not typing everything)

[ 65.471811] WARNING: at /build/buildd/linux-3.0.0/arch/x86/kernel/snp.c:118 native_smp_send_reschdule+0x5b/0x60() [ 65.472994] Hardware name: Z68MA-D2H-B3 [ 65.474174] Modules Linked in: snd_hda_codec_hdmi etc etc listed here was more of the the usb, bluetooth etc [ 65.474174] Pid: 2175, comm: alsa-sink Tainted: G D C 3.0.0-15-generic #25-Ubuntu [ 65.480694] Call Trace: [ 65.482005] [] warn_slowpath_common+0x7r/0xc0 etc etc. there were about 8 more lines of this [ 65.499909] ---[ end trace d33675238ae904cc ]---

does anyone have ANY idea how to fix this? I haven't installed anything recently, I have ALL updates.

This sounds like it could be a kernel panic. I'd suggest filing a bug report for this. – WarriorIng64 Jan 23 '12 at 2:02

This question should instead be filed as a bug report, and as such is off-topic, thanks! Instructions here. – jrg♦ Feb 1 '12 at 18:41

If the previous kernel (that is, 3.0.0-14) was working properly for you, I'd suggest using that for the time being until your issue has been properly filed as a bug report on Launchpad and fixed.

Unless you have removed the older kernel, to boot using it all you need to do is the following at each boot:

  • Start up your computer while holding the Shift key; do not let go until you see the purple GRUB menu come up. (Only necessary if your machine is not a dual-boot setup, in which case GRUB should come up automatically.)
  • In the menu, your 3.0.0-15 kernel should be listed at the top. Use the arrow keys to scroll down to either the first entry which lists 3.0.0-14 (not labeled as a Recovery Mode entry), or to the "Previous Ubuntu versions" entry where you should find the option. Press Enter to continue.

If it was truly the kernel giving you issues, the system should now boot and operate as normal.
