CVS commit: src/sys/dev



Module Name:    src
Committed By:   jdolecek
Date:           Tue May 19 08:08:51 UTC 2020

Modified Files:

        src/sys/dev/ic: mvsata.c

Log Message:
only start the timeout machinery once the I/O is completely setup
and successful, particularly after PIO write is finished

fixes crashes in case the setup is so slow that timeout is triggered
e.g. while still waiting in wdc_wait_for_unbusy() or shortly after, without
drive actually having chance to complete the I/O, as seen in some
configuration under QEMU by Paul Ripke
