Has Mr Gates been at the kernel source? (well you did say "evil"). Seriously
though, it's scheduler related. Someone please fix this as writing a cd now makes
my 2.2.10 system *UNUSEABLE* since I must have sound to work. Music keeps me
happy. Besides, when this happens, the processor load is all of 4% or so - hardly
enough to cause problems - since it happens on PCI hardware too - it aint my ISA
soundcard (SB 64 AWE Gold) - interestingly, it haoppens when ripping cd's too -
but cdrecord causes less than cdparanoia (my hdds are on one controller, the
cd-writer/cdrom are on the other.). I've already posted my machine specs but more
is available in someone wants. Howz about Alan/Linus comments on this so we know
once and for all? Thanx.
