What I possibly missed is that it is not guaranteed panic, and seems to be dependent on parameters of disk inserted: e.g. I usually have this particular machine panicked with WD320, and no panics with Seagate 7200.11/750G -- Sincerely, D.Marck [DM5020, MCK-RIPE, DM3-RIPN] [ FreeBSD committer: marck@FreeBSD.org ] ------------------------------------------------------------------------ *** Dmitry Morozovsky --- D.Marck --- Wild Woozle --- marck@rinet.ru *** ------------------------------------------------------------------------

It looks a bit too quiet. RELENG_7 branch ATA maintenance is a bit difficult for me now due to big differences from the HEAD. It makes me wish to sync them as there is still too much time before 7.x EOL. May be I will do it after the 7.2 release process finished. Now is probably not the best time to do it. -- Alexander Motin

For AHCI it is handled by masking interrupts during reset. How it is expected to be done here, I am not sure.
