>Description:
              after upgrading to 6.0RC1 and R I got HD errors like this 

Nov 26 08:32:35 nb kernel: ad0: FAILURE - READ_DMA status=51<READY,DSC,ERROR> error=40<UNCORRECTABLE> LBA=67582740
Nov 26 08:32:35 nb kernel: g_vfs_done():ad0s3e[READ(offset=8286093312, length=16384)]error = 5

Nov 26 08:32:38 nb kernel: g_vfs_done():ad0s3e[READ(offset=8286093312, length=16384)]error = 5
Nov 26 08:32:41 nb kernel: ad0: FAILURE - READ_DMA status=51<READY,DSC,ERROR> error=1<ILLEGAL_LENGTH> LBA=67582740
Nov 26 08:32:41 nb kernel: g_vfs_done():ad0s3e[READ(offset=8286093312, length=16384)]error = 5

on several PCs with ATA discs after system crash.

This with new and used ones. Since the erros could not be corrected by fsck i changed them.

This PC is a Notebook and I found the damaged block in a file in a user dir so I could use the PC still as another user.

I was booting then with hint.acpi.0.disabled=1 and to my surprise fsck identified the above error as DUPs and corrected them perfectly. I enabled acpi afterwards and the disk is clean.

I repeated this on another machine with a previous "uncorrectable" error and could repair it the same way. Other 2 disks I unfortunatly kicked into the trash :(
