panic "bio_completed can't be greater than bio_length" on CURRENT

Hi

Anyone seeing this?

panic("bio_completed can't be greater than bio_length")
kdb_enter()
panic()
g_io_deliver()
g-disk_done()
biodone()
ad_done()
ata_completed()
g_io_schedule_up()
g_up_procbody()
fork_exit()
fork_trampoline()

(Hand transcribed. Happens randomly, but most often soon after boot)
