The following reply was made to PR kern/14590; it has been noted by GNATS. From: "Matthew Emmerton" <matt@gsicomp.on.ca> To: <freebsd-gnats-submit@FreeBSD.org>, <miek@q8.se> Cc: Subject: Re: kern/14590: kernel panic writing to floppy Date: Thu, 3 Aug 2000 00:30:00 -0400 This is a multi-part message in MIME format. ------=_NextPart_000_000B_01BFFCE1.F532C6D0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable Using 3.4-RELEASE: The dd command using the char device (rfd0) works fine (no panic), but = using the block device (fd0) panics. On to the open->suspend rationale: Mounting a writeable floppy, pulling the disk, write-protecting it, = replacing it, and then writing to the FS results in a console message = complaining about writing to a write-protected media (expected), but = when the FS is unmounted, a kernel panic occurs.
