However, any attempt to use it causes a kernel panic, something about a spinlock. My other MIDI port (connected to a musical keyboard via a USB adapter) works fine. Both snd_mpu401 and snd_mpu401_uart load without problems. I thought this error might be related to 1623, so applied the supplied patch, but to no avail. ====================================================================== ---------------------------------------------------------------------- rlrevell - 12-07-05 21:18 ---------------------------------------------------------------------- Um, the SBLive! 24 bit does not have a MIDI synth. Please post the kernel panic here. ---------------------------------------------------------------------- Twey - 12-07-05 22:08 ---------------------------------------------------------------------- It doesn't? Ah, well that would explain the panic. Is there any way to disable the MIDI port ALSA creates so that applications don't try to use it? And... how exactly do I post a kernel panic? It goes by far too fast to memorize or write down. Is there a log? I'm thankfully inexperienced in the area of kernel panics :-) Issue History Date Modified Username Field Change ====================================================================== 12-07-05 20:56 Twey New Issue 12-07-05 20:56 Twey Distribution => Fedora Core 4 12-07-05 20:56 Twey Kernel Version => 2.6.14-1.1644_FC4 12-07-05 20:56 Twey Issue Monitored: Twey 12-07-05 21:18 rlrevell Note Added: 0006948 12-07-05 22:08 Twey Note Added: 0006950 ====================================================================== ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
