Synopsis: 9.0_RC1 kernel crash in ata_recovery_resume() (in NCQ support?)

State-Changed-From-To: feedback->analyzed
State-Changed-By: jdolecek%NetBSD.org@localhost
State-Changed-When: Fri, 24 Jan 2020 19:39:35 +0000
State-Changed-Why:
The crash happens because the recovery is eventually run via the kernel
thread, which countrary to the exception handler doesn't block further
interrupts during the processing. I'm working on making the recovery
path handle this correctly.
