I had the same slowdowns and soft lockups till 10 minutes ago, when i switched from cfq to anticipatory I/O. I'm currently usig 2.6.15-rc1 + reiser4 from 2.6.14-mm2 I was in the middle of a big gentoo'ish emerge, desktop almost unusable. but now with anticipatory all seems fine so far. the compile seems a lot faster. no soft lockup trying to use vim or locate... hmmm regards tom
