Btw, just FYI, I just tried the sysrq (using minicom CTL + A + F + 'magic key'), it works with system is running, but failed after I trigger a panic, I will check more though I'm not very familiar with sysrq yet.

Thanks! I'm not entirely sure if people still do this. I just saw the code in linux 2.4 and assumed that this still might be the case.

Well, "theoretically, why not" :) The system can panic() because of misbehaving video driver, for instance, so the emergency sync still should be possible.

But maybe it's all irrelevant, I don't know.
