BUG: soft lockup - CPU#0 stuck for 11s in linux 2.6.24-23

[James Tait]

I haven't been able to narrow this down to any particular activity, but it is definitely 2.6.24-23 that's the problem -- dropping back to 2.6.24-22 resolves this.

Ubuntu Hardy, fully patched, on Acer Ferrari 4005WLMi, AMD Turion 64 ML-37, 2GB RAM, BIOS revision 3A23. The frequent lockups are rendering the machine more-or-less useless. I have no modifications to the machine other than the RAM upgrade and no external devices attached.

This is not a bug in the linux-meta package, moving to the linux package.

Hi James,

Can you comment if this is still a regression for you with the 2.6.24-24 kernel for Hardy? Also, have you been able to test the latest Jaunty 9.04 release and confirm if this issue remains? It contains a newer 2.6.28 based kernel. http://www.ubuntu.com/getubuntu/download. Please let us know your results. Thanks.

I've been running Jaunty from a fresh install since Alpha 6 and haven't seen this problem. I don't recall whether or not I upgraded the kernel prior to reinstalling. Sorry I couldn't be more help.
