A newer driver version might fix things.
Hi, Today I tried pulling and compiling the drivers from the ALSA mercury repository and unfortunately the MPU port still won't work after a fresh reboot, the error messages are bit more verbose this time though: #rmmod snd-mpu401 snd-mpu401_uart; dmesg|grep pnp [17187495.568000] pnp: Device 00:09 disabled. #modprobe snd-mpu401; dmesg | grep pnp [17187550.044000] pnp: Device 00:09 activated.

Out of curiosity I tried booting an older knoppix with a 2.6.6 kernel (that only had OSS drivers...) and the system got hard locked by trying to enabe the MPU port. Cheers, -Giuseppe
