It means that the request was not sane anymore, or specifically that clustered number of sectors was set to lower value than current number of sectors (which isn't valid, of course). The buffer-list destroyed comment tells you that this corruption is most likely due to the buffer_head list on the request having been corrupted -- which in turn probably means that someone seriously screwed this request. hda8: bad access: block=5296, count=-2 end_request: I/O error, dev 03:08 (hda), sector 5296 hda8: bad access: block=5298, count=-4 end_request: I/O error, dev 03:08 (hda), sector 5298 hda8: bad access: block=5300, count=-6 end_request: I/O error, dev 03:08 (hda), sector 5300 This errors would seem to backup that theory :-) Is this an SMP board? Also, is end_request: buffer-list destroyed the very first error message? -- Jens Axboe
