Currently xmonad on my laptop is causing a very high number of wake ups (about 100 wake ups per second, measured with powertop), draining the battery life dramatically. This was fixed in GHC 7.4.2 ( http://hackage.haskell.org/trac/ghc/ticket/5991 ), so if possible I would like to request a version bump or backporting the patches. My configuration (related to xmonad): - Kernel 3.4.4 - AMD64 (gentoo-sources) - GHC 7.4.1-r1 - XMonad 0.10

This is a pretty major issue, especially for laptop systems. I confirm it as well.
Comment 2 Joe Kappus 2012-09-15 08:05:04 UTC
Oh I just wanted to add. Bumping to 7.4.2 does *not* fix this. The tracker linked above confirms this as well.

Does ghc-7.6.3 work better for you on this workload?
Comment 4 Joe Kappus 2013-07-29 14:44:45 UTC
Yeah, looks ok for me now. I think I remember seeing patches committed for 7.6 that fix the issue.
