Hi,
on one particular machine, an IBM workstation (Intellistation A Pro with dual opteron 250, 4GB RAM), opening a rawmidi input port on an M-Audio 2496 card will cause an immediate reboot of the machine. I've tried with different SMP kernels and different ALSA versions (including 1.0.14rc3), but always the same. Syslog does not show anything.
Using a USB MIDI interface works fine. Also, MIDI input on a similar workstation (Intellistation Z Pro, dual xeon, 1GB RAM) with M-Audio 2496 works without problems.
Any ideas?
Hm, this sounds like a problem of ice1712 driver, not the rawmidi core side. Though, the symptom is a bit puzzling; most of mpu401 problems is the lock-up rather than an immediate reboot.
Or, do you set up the machine to do automatic reboot at a kernel panic?
