Unfortunately, Tyan's support for BIOS updates seems to be very poor. I have put the tested M Audio Audiophile PCI sound card in the second test machine (identical configuration, Opteron 240, 1GB RAM except for motherboard, which is an ASUS SK8V. The Linux distribution installed is 64 Studio version 0.5.3 with kernel 2.6.13). MIDI appears to work perfectly in the second machine - at least I can get output from amsynth, and I can't reproduce the lock-up. I therefore conclude that there is a motherboard/BIOS bug or a random hardware fault on this particular Tyan Tiger K8W S2875 board which causes the hard lock-ups when MIDI is used, but only on an envy24 chipset card - it works fine with an EMU10K1 card such as a SoundBlaster Live. Weird, huh? Thanks for all your help! Daniel ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc. Do you grep through log files for problems? Stop!
