Hi Andrew,
aacraid-fix-shutdown-handler-to-also-disable-interrupts.patch is meant
to ensure that we don't perform an unnecessary reset of the device
during a kexec boot. During kexec, we perform the device_shutdown()
which should bring the device to a known sane state and a reset is
not required while next kernel is coming up.
I think this fix just masks Yinghai's problem and as such does not
fix the root cause of the problem. In his case a software reset
of the card is not successful and this is a problem. This problem
will become visible during kdump.
So I would think that this regression is still there just that got
shifted from kexec to kdump.
But we do need above patch to make sure kexec boot is fast and does
not perform any unrequired device reset.
Thanks
Vivek
