I just got a different trace, but same file with today's 4.99.65 amd64 (on
dual core):

assertion is "!cv_has_waiters(&bp->b_done)" failed in vfs_bio.c:950
stopped in pid 0.46(system) == raid0

bdirty() +0xbe
softdep_disk_write_complete() +0x36a
biodone2() +0x19
rf_State_LastState() +0x76
rf_ContinueDagAccess() +0xf4
DAGExecutionThread() +0x123

only "local" is in "biowait"

(root on raid1, with softdeps)
