Done a lot of testing now: * Disabled all debugging (to serial and debug info on syslog) -> No change. * Used #define KDEBUG_LEVEL 0 -> No change * Removed all drivers except those necessary (isa, pci, scsi, ata, vesa, usb, hda and a few others left) -> No change * Updated Rudolf's patch from http://dev.haiku-os.org/ticket/3356 to current -> No change. I guess I'll try Cian's suggested patch here: //www.freelists.org/post/haiku/HDA-audio-driver-more-testing-possible-patch as well. I'm not really sure what to do else except hunting sections with interrupts disabled and proof-reading mediakit code. /Fredrik Holmqvist, TQH
