Anyone experiencing instability with BFS patch-set?
I'm using kernel26-ice with BFS patchset, and in the last 3-4 weeks I noticed jerkiness sometimes, and the machine hard-locks every day or so, during periods of low CPU usage. Anyone else here using -bfs and can comment?

I'm using kernel26-ck with BFS enabled, and I'm not having anything of the sort either. Though, my computer is never at a low CPU usage.

Re: Anyone experiencing instability with BFS patch-set?
Hmm, I only get this with BFS on kernel26-ice. May try out kernel26-ck one day. If I disable BFS things work fine. Similarly it happens most often with compiz, can hardly get any issues if I switch back to metacity.

I use BFS/tuxonice (zen) no problems.
Out of cutiosity, how can you disable cpu scheduler (unless this is not BFS cpu scheduler)?

Latest BFS there's an option not to use it during 'make config'. I also just recompile the kernel without that patchset (my preferred method).

Re: Anyone experiencing instability with BFS patch-set?
I have not seen BFS as optional in kernel26-ice config (one published in AUR http://aur.archlinux.org/packages.php?ID=15224 ), that is why I asked. zen has BFS as an option in -rcX unstable.

^ one of the reasons I dont like kernels (and nvidia) from PKGBUILD 
$cat /usr/src/zen-unstable/.config | grep -i bfs
CONFIG_SCHED_BFS=y
CONFIG_SCHED_BFS_AUTOISO=y
CONFIG_SCHED_BFS_CUSTOM_RR=y
CONFIG_SCHED_BFS_RR_INTERVAL=3
everything in one place: kernel config file

Re: Anyone experiencing instability with BFS patch-set?
Your kernel config file cannot determine what patches to apply.... the PKGBUILD can.
