A bit more investigation shows it's panic'ing with "privileged instruction in non-priviliged mode" in what appears to be lseek(). This may or may not be related to the DMA TIMEOUT problem as I didn't see any timeouts before any of the panics I've witnessed. A bit more reading around suggests that the timeout issue is strongly related to my SI3112 SATA controller so I'm thinking of changing it; can anyone please recommend an SATA controller they're using which hasn't given them any problems? (Even better if they have Maxtor drives hanging off it!) I am also attempting to upgrade my system to a newer cvs but unfortunately I can't buildkernel on it - it'll either panic or generate enough timeouts to make "make" fail. If anyone could point me at a HOWTO or similar on cross-compiling then I'll compile it on my other machine instead (2xP3-1Ghz vs my desktop being an Athlon XP 1700+). All help appreciated as currently my desktop is becoming unusable and I fear for the safety of my data with the sheer number of panics being generated by disk use :)
