I run kernel 2.0.14 (SMP) on a Tyan Tomcat II, with 2 P120s. My sound card is a Sound Blaster AWE32 Value (ct3910). The sound card is initialised to use IRQ 5 by the DOS driver.
When I insert the sound module, it often fails to initialize the card. Sometimes, though, it manages it.
Patches added to kernel: Plug'n'Play BIOS support (the card isn't PnP, so I don't suspect this) PC speaker driver AWE32 driver
Is this a problem with the SMP interrupt handling? Could this be a manifestation of the problem that older versions this motherboard are reported to have with CPUs at or above 120MHz and 512Kb cache? I was assured that it had been fixed when I ordered the board.
What is the current kernel version regarded as stable for SMP? The most recent information I could find says don't use anything >= 2.0.15 because the interrupt handlers are broken, but that was two months ago. Are they fixed yet?
If you want a dmesg output from boot, look at http://dwmw2.robinson.cam.ac.uk/cgi-bin/dmesghtml
