I think CONFIG_PREEMPT is still not safe on PPC. If you enable CONFIG_PREEMPT and CONFIG_SMP on ppc32 (even if this is a uniprocessor machine), Preemption works quite fine. I use it now for about two weeks on my G3 and G4 with a 2.6.10 and a 2.6.12_rc5 kernel. Yes, enabling CONFIG_SMP seems to fix the problem. Been running for two weeks now, with no issues. Downstream bug report: http://bugs.gentoo.org/show_bug.cgi?id=86544 Does this behavior still occur on the latest kernels? Nope. I can use PREEMPT without SMP enabled. It's working since 2.6.16 or so. Thanks Lars. Closing this bug out then. |
