Well, I just enabled FULL_PREEMPTION in my kernel conf and things are=20 MUCH better, but the problem still reproducible when I check mail on=20 all of my e-mail accounts in kmail. Kmail forks off a process to=20 check mail, and since I've got about a dozen accounts I get the=20 jerkyness of the mouse for a couple of seconds while all of them are=20 racing for the processor trying to check mail. The behavior is much=20 less pronounced and I can now play music and compile stuff without=20 skipping and freezing. =2D-=20 Anish Mistry --nextPart4889733.elu790VgPS Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.4 (FreeBSD) iD8DBQBHF6ZOxqA5ziudZT0RAjUiAKDMve4K5Pkfh4FJKUSWgRdRluB8/QCgk/hq dhxHBaxEyNUQklAuhi3ZyB4= =9ku6 -----END PGP SIGNATURE----- --nextPart4889733.elu790VgPS--
