sometimes. The other times the machine simply freezes without any notice
in the logs.
Im suspecting an interrupt handling problem since both USB controller(no
usb devices attached) and maestro3 are sharing interrupt 5:
00:07.2 USB Controller: Intel Corp. 82371AB PIIX4 USB (rev 01)
00:08.0 Multimedia audio controller: ESS Technology ES1988 Allegro-1 (rev 12)
and this only seems to happen after using the maestro3 module. I'm using
the alsa maestro3 driver as of 0.9.0beta10a. 2.4.13 + kernel's maestro3
worked fine though.
