Since I upgraded from 5.3-stable to 5.4-prerelease, I've noticed that my computer is hanging badly under load. I've a P4 2.53 GHz without hyperthreading (no SMP). I use the same kernel configurations than before. Now when I compile a port for example, the mouse pointer hangs in Fluxbox and Mozilla takes forever (meaning ~5 sec) to refresh the screen. Even vi hangs. I do not see any warning/error message. Is it a known problem with 5.4? Thanks Pierre-Luc Drouin

Is it a >known problem with 5.4?Not quite as dramatic here, but when, say, the firefox source gets untarred, my machine becomes quite unresponsive, including audio decoding (xmms) stuttering and the mouse cursor jumping around. Haven't seen the likes since the 486 days. This is 5.4-PRERELEASE on a P4 3GHz. Perhaps some badly balanced scheduler stuff? mkb.
