[ 6.329161] CPU1: Not responding. Hm. What kernels worked on F15 and what kernel did you use with openSUSE 12.1? Also, given it seems to be an upstream problem, could you report this to the linux kernel mailing list? See also: bug 648837, which is happening on an AMD Phenom II processor.

dmesg output on Fedora 15 after update with only 1 core being active
Most of the time only one core is active. The system freezes also.
Josh Boyer, I did a small research. After installation of F15 everything works fine. Kernel is 2.6.38.6-26.rc1.fc15.x86_64. Right after update (kernel 2.6.41.1-1.fc15.x86_64) the problem appeared. I've never did this update before because I installed F15 only few weeks ago and upgraded to F16 directly. So, the behavior of F15 after updating to kernel 2.6.41 and of F16 with kernel 3.x is the same. Sometimes you can boot with both cores being active. But this case is very rare. Most of the time you will have only one active core. And the system will freeze in both cases after 5 minutes. There was recently a regression fix in the ACPICA code that impacted a number of Pentium based machines. Could you try the 3.2.8 kernel in F16 updates-testing and let us know if that helps?

Seems like I have no problems running even 3.2.7 kernel without using updates-testing repo. dmesg outputs attached. OK, great. Thank you for replying. |
Created attachment 537153 [details] dmesg output Compaq Presario CQ56-118EO with Intel Pentium Dual Core T4500 CPU. Only 1 CPU core is active. And CPU is fully loaded every time. System freezes after 5-10 minutes after booting. I've noticed also that Caps Lock indicator is always on irregardless of actual caps lock status. I've upgraded from F15 to F16. Then tried also clean install. Exactly the same problem with openSUSE 12.1.
