[CentOS] kernel BUG at fs/bio.c (kernel 2.6.9-34.0.2.EL)

Hi folks,

Backing up a host as noted below im getting over and over again the same issue
on actual kernel, details:

- Backup host has a pci/usb2.0 card, with a 250gb usb 2.0 disk attached,
- Celeron 900 family
- Remote host, local console from boot linux rescue:
  # dd if=/dev/hda conv=sync,noerror | ssh -c blowfish root at 192.168.0.6 "dd
of=/media/backup/vol-hda.raw.img"
- Backup host (192.168.0.6), kernel bug from netdump - here spoolbox host- as
netdump-server:
