"AARRRGGGHHH just as it seems everything is working it all falls apart
again.

findings so far..
1. it doesn't appear to be restricted drivers , as removing them seems to
make no real difference
2. If system is stable for more than 30 minutes it will generally stay up
all day
3. no acpi etc changes have no beneficial effect on my system
4. possibly rt61 drivers??

anyway trying the 386 kernel to see if that helps? so far so good but wont
give a definitive thumbs up for a couple of days, as sods law it'll soon go
belly up"
