--- Comment #12 from Roger Luethi rl@hellgate.ch 2011-11-10 00:24:39 PST --- Like Jürg Billeter, I haven't seen the problem since switching to Linux 3.1.
I don't currently use the affected system as much as I usually do, so it may be too early to celebrate, but I guess the bug could be closed as resolved and reopened later if need be.
