Booting halts when using USB drivers (not even able to get into KDL) and without them, but then i can go into KDL and type "outb 0x4d0 1" "continue" and it boots fine after that.

Copying some of my random musings from IRC.

DHowett: MrSunshine: Hmm. 4d0 is ELCR1, which linux updates in its acpi-related boot code.
Haiku doesn't touch it in its acpi bus manager. Interesting.
DHowett: Haiku used to set everything to level-triggered. writing 1 to 4d0 sets int0 to level-
triggered and everything else (int 1-7) to edge-triggered
DHowett: maybe it would resolve it to just set the timer to level-triggered mode on boot. but I
don't know what that would cause for systems other than yours.
