>Description:
      Using a Promise FastTrak100 TX2 ATA RAID card connected to mirrored 20GB ATA/133 drives, the system panics after getting a UDMA ICRC error reading fsbn xxx. The panic is Fatal Trap 18: integer divide fault. Happened on an Intel Celeron 1GB Motherboard, swapped MB for ASUS MB and repeated. Maxstor drives. Seemed to follow one drive, switched that drive with IBM travelstar, faulted on the other Maxstor.
Promise card is using latest BIOS (2.00.0.24). Maxstor drives pass all Maxstor diags. ar0 is the array, ad4 is the first drive and ad6 is the second drive. The subdisks come up as atax master UDMA133, which seems odd, as the card is supposed to be ATA100.
>How-To-Repeat:
Basic install, only thing strange is the IDE mirror set. Not consistent, sometimes did not appear until rebooting a dozen times. Faults while booting.
