[...] There have been reports of this in Debian going back to 2.6.39: http://bugs.debian.org/631187 http://bugs.debian.org/636263 http://bugs.debian.org/642043 Plus possibly related crashes in elv_put_request after CD-ROM removal: http://bugs.debian.org/633890 http://bugs.debian.org/634681 http://bugs.debian.org/636103 The former was also reported in Ubuntu since their 2.6.38-10: https://bugs.launchpad.net/debian/+source/linux-2.6/+bug/793796 The result of the discussion there was that it appeared to be a regression due to commit 86cbfb5607d4b81b1a993ff689bbd2addd5d3a9b ("[SCSI] put stricter guards on queue dead checks") which was also included in a stable update for 2.6.38. There was also a report on bugzilla.kernel.org, though no-one can see quite what that says now: https://bugzilla.kernel.org/show_bug.cgi?id=38842 I also reported most of the above to James Bottomley and linux-scsi nearly 2 months ago, to no response.
