Hi Craig, Sorry for the delay - couldn't get to writing it up until now. Here's the backtrace: Tracing pid 3 tid 100011 td 0xc3a19000 _mtx_lock_flags (1c, 0, c6cd24a7, 1d8, c6ba6ad4, ...) at _mtx_lock_flags+0x46 vdev_geom_io_intr(c6ba6ad4,0,c0a9b395,bc5,c6ba6ad4,...) at vdev_geom_io_intr+0x41 biodone (c6ba6ad4, c0ba4488,24c,c0a89c98,64,...) at biodone+0x99 g_io_schedule_up(c3a19000,0,c0a8b393,5d,0,...) at g_io_schedule_up+0xc7 g_up_procbody (0,dc6c4d38,c0a8eced,315,c3a5d2ac,...) at g_up_procbody+0x8d fork_exit(c06fe7e0,0,dc6c4d38, at fork_exit+0xb8 fork_trampoline() at fork_trampoline+0x8 --- trap 0, eip = 0, esp = 0xdc6c4d70, ebp = 0 ---- If it's relevant, the backtrace is typically preceded by a number of UDMA ICRC errors on the console naming an LBA value (which varies). Then I'm given the debugging prompt. Cheers, Thede Craig Rodrigues wrote: > > > On Wed, Jul 18, 2007 at 09:46:22AM -0700, Thede Loder wrote: >> >> Hi Craig, >> >> Will do.
