*RedHat* Linux 6.1 installs an aic7xxx driver on an SMP PII system. Now I know why it doesn't work all the time (timeouts, lockups).

Why not, when I wrote a Linux video driver I just protected everything shared between h/w and s/w with a spinlock so only one s/w element at a time would touch it. Okay, also interrupt s/w and non interrupt s/w, but you get the idea...
