Sigh. In the last three days I've had no fewer than four crashes: This one, another just like it that I didn't get a dump for, a "Fatal trap 12: page fault while in kernel mode" in buf_splay(): #27 0xffffffff802e2cb4 in buf_splay (lblkno=0, xflags=2 '\002', root=0x9000) at /usr/src/sys/kern/vfs_subr.c:1339 #28 0xffffffff802e2e08 in buf_vlist_remove (bp=0xffffffffa1919340) at /usr/src/sys/kern/vfs_subr.c:1371 #29 0xffffffff802e4dab in brelvp (bp=0xffffffffa1919340) at /usr/src/sys/kern/vfs_subr.c:1502 #30 0xffffffff802d28f1 in getnewbuf (slpflag=0, slptimeo=0, size=2, maxsize=16384) at /usr/src/sys/kern/vfs_bio.c:1801 (where bp->b_left is 0x9000) and a "panic: backgroundwritedone: lost buffer." I have a dump for each of the three unique scenarios. At the moment I've dropped back to the older kernel and am keeping my fingers crossed that it will run okay. I'm beginning to suspect hardware, although as two of the three are in the buf code there might be a problem there... If it continues with the older kernel then it is most likely hardware but if not then there's a problem.
