hi there,
how different is the code path between reboot(8), halt(8)
and when i press the power button?
the reason i ask is, that fairly often, reboot(8) and halt(8)
"hangs" (X disappears, but there is only black screen,
and the console never appears, no "syncing disks" message),
but pressing the power button turns off the machine
without fail every time. another one of those mysteries..
happened on multiple notebooks for me, but here is the dmesg
for the one i use daily nowadays.
