dmesg including blkid triggering BUG
dmesg on 3.3-rc7 i386 |

You obviously have a PL3507 based disk enclosure, and the udev helper scsi_id triggers a firmware bug. See thread "Unable to access firewire hard drive" at linux1394-user, http://marc.info/?t=132975440900001 Created attachment 72571 [details]
dmesg on 3.3-rc7 i386
Thanks! Disabling scsi_id worked. OK, so it is indeed the same issue, and not a kernel problem. But let's keep this ticket open as a reminder until I have a proposal for a fix (in udev rules or scsi_id or wherever). |
Created attachment 72570 [details] dmesg including blkid triggering BUG I have an external drive with both USB and firewire. When using the firewire connection I can not mount the partitions (or identify them with blkid). I dd'ed the disk and partitions both via usb and via firewire and compared the results, and it seems like everything is shifted 8 bytes on firewire. If I use "blkid -p -O 8" I can successfully identify the partitions via firewire. I have tested this both on my PowerBook G4 (powerpc) and Acer TravelMate 8100 (i386). Under MacOSX 10.4 both firewire and USB work fine.
