| |
Salut,
I happened to notice that under Linux 2.6.0-test[1-9] timer interrupts appear not to be fired at all unless another interrupt happens. This has been shown by some weird behaviors:
1. sleeps on boot can take an infinite amount of time, but if I press any key, the booting will continue at once.
2. If I call date on a console when the PC is idle, each call to date will show exactly one second more, even if I waited ten seconds.
3. When I do something like playing ogg streams, the clock runs at its usual rate.
I didn't see any of these problems on Linux 2.4 or FreeBSD 4.8, but FreeBSD 5.* behaves in a strange way, too: the clock will run at double speed.
(Another probably bad thing: The NVidia framebuffer driver doesn't appear to work well for me: if I switch to more than 800x600@85, the monitor switches itself off. Note, however, that 2.4 is working well at 1024x768@100.)
