I'm having trouble with the recently released kernel 2.6.19 from
kernel.org. With kernel 2.6.19 installed (my custom build from
sources), my system freezes at random points within several hours
after reboot.
A noticeable symptom is blinking CapsLock and ScrollLock keybord leds
(but not NumLock).

I noticed this blinking yesterday, during an unrelated kernel panic
(disk driver wasn't there).
The kernel was complaining about the keyboard's interrupt and the blinks
were in sync with that message.

I believe those LEDs blink when the kernel panics. If you are not
running X at the time you should see t

Because that is quite a complex task on a modern graphics card. Usually
there is no way to switch to a mode (be it text or gr

Maybe it's just the kernel telling you the reason via CapsLock LED morse code ?
IIRR there was such a emergency module in 2.6.19 devel branch.
I'm sorry ;) Finally, keep it with humor
Good luck anyway, Micha

Or netconsole (esp. in case of newer laptops without any serial ports),
but in both cases _ONLY IF_ you have something to attach at the other
end of the cable. The big problem is
