I have had an awful weekend trying to make sense of wild errors that FreeBSD has been throwing on my VIA EPIA M1000 board. 5.0 seemed to be going fine, until I tried to make buildworld using 5.2.1 sources. Then it crashed and reset halfway through. The second attempt worked, so I built and installed a 5.2.1 kernel. Then the fun began. 5.2.1 would not accept my hard disk. Attepmting to boot normally, or mounting drives after booting into single-user-mode, would cause a stream of errors. Thinking the crash had screwed my hard disk data structure, I did a fresh install of 5.2.1 from the release ISO from the FTP site. Booted fine on a Pentium 4 machine, but went beserk again on my EPIA board. The error I'm getting looks like this: ad0: FAILURE - WRITE_DMA status=11 <DSC,ERROR> error=84<ICRC,ABORTED> LBA=4127103 Such messages would stream up the screen, the drive crunching wildly. Any successful access (booting from a kernel.old 5.0 kernel, for instance) would complain about the filesystem being dirty, and leave the system read-only until fsck was run. fsck would run, but would find dozens of assorted errors which it could not correct. I posted this to freebsd-questions, and someone replied with something along the lines of 'me too' - they say that they can run 5.2.1 on a Compact Flash card, but will get wild problems too if they attempt to boot it from any hard disk. Also, should it be of any interest, I can only run 5.0 if I disable UDMA access to the Primary IDE Master in my BIOS settings. FreeBSD obligingly drops to PIO mode. Any ideas on this? -- Bob
