Thanks for reporting it, and sorry for the slow response. Some questions: - what kernel are you using now? - can you still reproduce this? - can you reproduce it with a squeeze kernel, too? - do you know what exact version the working 2.6.32-gentoo kernel was? - please attach a log of the initialization of the kernel, either by saving full "dmesg" output right after booting or by gathering it from /var/log/dmesg* - any workarounds or other weird symptoms? If you can reproduce this reliably with a 3.1.y kernel, we should take this upstream (looks like that's linux-...@vger.kernel.org plus linux-ker...@vger.kernel.org; please cc me or this bug log if writing there so we can track it).
