I also am running a BP6. IS ANYONE successfully running an ABIT BP6 motherboard on a SMP kernel with -current? What BIOS version are running? I'm one version behind I think, so I'm going to upgrade and see if that makes any difference. > The same machine runs happily strings of make -j48 buildworld's when > running with the straight GENERIC UP kernel, so I think the hardware > seems to be working OK. I haven't tried anything that drastic, but I have had NO crashes or lockups that I couldn't explain in a NON SMP kernel. The SMP kernel on the other hand will Hard Lock anywhere in anywhere from seconds to days. It seems to be more likely the harder I push it. I don't think its the hardware. I've pulled my hair out and tried everything I can think of to eliminate the possability of it being hardware. I'm hoping that dnet causing a panic is somehow related. > Even make -j1 buildworld with the SMP kernel ends with a complete > freeze of the machine (the kernel does not go to a panic where I > could try a backtrace) Exactly! Hard Lock, no panic, no keyboard, no choices other than = reset. > The hardware config of the machine is pretty dull (see dmesg later). > > One point that could be better is that the sources are NFS mounted > from a 4.7-Stable server, over an rl(4) board, which may be unstable > (/usr/obj is local, on the Maxtor drive) All my harddrives are local, 3 SCSI and 3 IDE. > . . . snip . . .
