Several errors have occurred where the adapter stops or fails but does
not raise the register values for the driver to detect failure. Thus
driver is unaware of the failure. The failure typically results in io
timeouts, the io timeout handler failing (after several seconds), and
the error handler escalating recovery policy and resulting in more
errors. Eventually, the driver is in a position where things have
spiraled and it can't do recovery because other recovery ops are still
outstanding and it becomes unusable.
Resolve the situation by having the io timeout handler (actually a els,
scsi io, nvme ls, or nvme io timeout), in addition to aborting the io,
perform a mailbox command and look for a response from the hardware.
if the mailbox command fails, it will mark the adapter offline and then
invoke the adapter reset handler to clean up.
The new io timeout test will be limited to a test every 5s. If there are
multiple io timeouts concurrently, only the 1st io timeout will generate
the mailbox command. Further testing will only occur once a timeout
occurs after a 5s delay from the last mailbox command has expired.
