The following reply was made to PR kern/153511; it has been noted by GNATS. From: Colin Percival <cperciva@freebsd.org> To: bug-followup@FreeBSD.org, cperciva@freebsd.org Cc: Subject: Re: kern/153511: [xen] [panic] kernel panic when xen disk is detached Date: Wed, 29 Dec 2010 08:08:54 -0800 This panic is happening because we don't have a .pic_disable_intr -- when the interrupt is being killed, pic_disable_intr gets invoked which doesn't work very well when it's NULL. I have a patch which seems to fix this panic, which I'll commit later today or tomorrow assuming no problems turn up in further testing. -- Colin Percival Security Officer, FreeBSD | freebsd.org | The power to serve Founder / author, Tarsnap | tarsnap.com | Online backups for the truly paranoid
