With this new one I cannot boot any more (I also updated the source
tree). This is a hand transcripted version:
Trying to mount root from zfs:zroot/root []...
panic: Batch flag already set
cpuid = 1
KDB: stack backtrace:
db_trace_self_wrapper()
kdb_backtrace()
vpanic()
kassert_panic()
xpt_batch_start()
ata_interrupt()
softclock_call_cc()
softclock()
ithread_loop()
fork_exit()
fork_trampoline()
Thank you for the report. I see my fault. It is probably specific to
ata(4) driver only. I've workarounded that in new patch version, but
probably that area needs some rethinking.
