I just expected crtl+del+alt to do something because it triggers(or is supposed to trigger) an interrupt. Would X hanging like that also disallow F* to a tty? I tried to get to a terminal, but couldn't.


Ctrl-alt-backspace... Last time i checked, though, no specific key combination has it's own IRQ in any pic.

Yay for bringing old threads back from the dead! Anyway...

They panic() instead of showing a BSOD Wink


What this means is that instead of locking up the system and potentially rebooting, it makes a log entry and continues without the problematic driver. AFAIK Linux runs drivers in ring1, so there is much more control here than in Windows where everything except userland is ring0.

I've had Linux running as a server on totally fried hardware (bad memory, overheated motherboard and dead harddrive) and it just kept on going, albeit processes kept vanishing and when a process wanted to I/O something to disk larger than the cache it froze. But the system kept on working!

On the other hand this palm with Windows CE on it I had is practically useless as nothing saves anything over a reboot (for example the WLAN driver had to be reinstalled on every reboot) and it tends to mess up every now and then requiring a reboot.

So... uh... yea. Linux is more reliable I think. Lol.

LP,
Jure
