the hardware: nforce4-a939 mlb with a Athlon64 3800+ (dual core), 4G ram, 2x3-ware PATA cards (with 12x300G seagate drives), Adaptec 3120S raid controller with 2 pairs of scsi drives
I've been having problems with this new machine locking up so I turned on just aobut every debugging option and setup a serial console, the full boot log (1.5M of it) is at http://lang.hm/linux/boot_log but the relavent portion of it seems to be blocks of the following errors
slab error in cache_free_debugcheck(): cache `i2o_iop0_msg_inpool': double free, or memory outside object was overwritten

I think I saw a compile-time error flash by (something about a cast between incompatable pointer types).
the kernel config is also on the website at http://lang.hm/linux/config
as this is a new box that I have not gotten working reliably yet I can't conclusivly rule out hardware problems. it's survived 48 hours of memtest86 and the various controller cards were out of an older system so they should be good.
