I get a problem on several am2 motherboards when an SCSI Adaptor (LSI or Adaptec) is installed and with 4Gigs of Ram the problem is easy to repeat, after some minutes compiling world the machine crashes, sometimes a panic mmap ffs crossrefeerence or something, passes too fast to look an when the machine comes back often the complete root partition is gone or if not it needs manual fsck and mostly /dev references are gone or other important parts so the disk isn't bootable anymore funny is (for me) that the other partitions are ok ever and only root is fucked ever I tried MBs as Asus, Abit and Gigabyte all same result Same hardware with SATA works perfect Same hardware with scsi up to 3.5Gigs installed works perfect what calls my attention that all this MBs do not have the memroy hole remapping feature so the complete 4gigs are available what normally was not the case with amd64 Mbs for the Athlon 64 CPUs some has an opinion if this is a freebsd issue or MB falure or scsi drv problem? Gigabyte support tips a driver problem and no MB issue. Other manufactures don't answer. regarding the SCSI I tried the LSI U320, Adaptec U320 and Adaptec Raid SCSI (aacd) and all of them give me the same problem -- Jo?o A mensagem foi scaneada pelo sistema de e-mail e pode ser considerada segura.

Is the compiler using /tmp and /tmp is in root partition? Maybe try having a seperate partition for /tmp, might keep root partition from getting trashed?> Same hardware with SATA works perfectMaybe try root partition on SATA, everything else on SCSI and see what happens. If the system supports a RS-232 console, you could capture panic message that way. Or aim a video camera at the screen.

If you want to use SCSI then you'll have to limit memory to 3.5 GB. --- Gary Jennejohn
