src/sys/dev/ic [jdolecek-ncq]: mvsata.c
Log Message:
fix condition for switching to kernel thread for ATAPI and bio reset recovery
to match atapi_wdc.c, __wdcwait() postpones to the thread whenever neither
AT_POLL nor AT_WAIT flags are present
fixes spurious 'timeout' for the command on mvsata, followed by 'unexpected'
interrupt
