Laferriere" <babydr@...y-dragons.com> To: linux-raid maillist <linux-raid@...r.kernel.org>, Linux Kernel Maillist <linux-kernel@...r.kernel.org> Subject: raid5:md3: read error corrected , followed by , Machine Check Exception: . Hello All , I was under the impression that a 'machine check' would be caused by some near to the CPU hardware failure , Not a bad disk ? I was also under the impression that software raid s/b a little more resilient than this . But then maybe one or the other of the subsystems walked all over the other one trying to correct itself . Who knows . The below is ALL I'll be able to get . A log of a previous boot is available at ... http://www.baby-dragons.com/test-2.6.21.5-mptscsi-4.00.10.00-2007006161326.log Tia , JimL filesrv2 login: Jul 14 22:58:48 filesrv2 -- MARK -- Jul 14
