I saw something like this on my thinkpad (RH6.2)
and it turned out to be connected to /etc/adjtime .
It was cured by changing the large numbers in
there to zeroes.

Could someone explain the mechanism?

There have been at least five holes found in pile that _could_ have been
exploited, and even one in all xterms pre X11R6 where ascii+escape codes
was all you needed.
Mutt has had minor things fixed for security reasons too.

It's harder. But you ignore two things - once someone does it anyone can
repeat it - and more importantly almost all exploits rely on user error.
Linux users are not always brighter than windows ones and there isnt a lot
you can do to make them smarter

Think of computer security like powertools. The day you think you are totally
safe is the day you end up hurt.

Laptop system clock slow after suspend to disk. (2.4.0-test9/hinote VP)

[Ian Stirling]

I've not noticed this on earlier kernel versions, is there something
silly I'm missing that's making my DEC hinote VP (p100 laptop)s 
system clock slow by a factor of five or so after resume?
Not the CPU or cmos clock, only the system clock.
Thoughts welcome.

Try this.
