The system just hangs randomly, more often when on-load. Nothing is left on the logfiles, but I was able to get a trace of the kernel panic via network console (see the next attachment). I have tried using sys-kernel/vanilla-sources-2.6.29.4, but I have the same problem with it. sys-kernel/gentoo-sources-2.6.27-r8 works fine, and the configuration used for these newer kernel comes from the configuration used for this kernel (with some minor modification). Another symptom is a noisy whine when the CPU is idle. Reproducible: Always Steps to Reproduce: 1.boot 2.do some stuff 3.

Does it occur with gentoo-sources-2.6.30-r2?
I have been using gentoo-2.6.30-r{2,3} for three days without issues now: as I was always able to reproduce this bug within 4-5 hours of use with the older kernels I guess that 2.6.30 actually fixes the bug.
