My mouse moves choppily and keyboard misses keystrokes, if I copy something big to a USB flash load increases to 2.5+. Random X crashes but I'm using ~x86 for it so that might be unrelated. Works fine with vanilla-sources 2.6.27.12, no packages changed.

FYI I also tested with 2.6.25-gentoo-r9 which I used before switching to this new MB & CPU but it has the same issue. Just writing to a usb flash is enough to get a load of 1.5-2.
If you're really using ~x86 then you should be able to quite easily test whether a 2.6.28 version fixes the USB issue - a lot of USB stuff was changed for the 2.6.27 release and only 2.6.28 really got it right, IIRC.
Have you tested with gentoo-sources-2.6.28-r2?
Works fine with 2.6.28-gentoo-r2, thanks for the tip. I was using ~x86 only for X and related stuff, not for everything. With this kernel it seems like load increases a lot too (up to 2) but the UI is still responsive and no choppy sound artefacts. I guess that's the usual :-)
Um, this is not a support forum. A bug is fixed when a fixed version goes stable to replace an unfixed version, not when your personal problem has been fixed.
OK, sorry. FYI 2.6.28-gentoo-r2 is better than vanilla 2.6.27.12 so it might as well be an upstream issue.
gentoo-sources-2.6.28-r8 contains up to linux-2.6.27.19 and some additional patches. Would you mind testing vanilla-sources-2.6.27.19 and posting the outcome? Thanks.
Martin, do we have any news? Did you test vanilla-sources-2.6.27.19?
