Hello,

I have an Adaptec 2940UW and a Fujitsu M2952Q disk. 
Here are the relevant boot messages on FreeBSD 2.2-961014-SNAP
kernel:

Nov  4 14:25:34 chaconne /kernel: ahc0 <Adaptec 2940 Ultra SCSI host adapter> rev 0 int a irq 15 on pci0:17

I am now getting repeated messages such as and lots of I/O errors:

sd0(ahc0:6:0): HARDWARE FAILURE asc:44,84 Vendor Specific ASCQ
, retries:4
sd0(ahc0:6:0): HARDWARE FAILURE asc:44,84 Vendor Specific ASCQ

sd0(ahc0:6:0): HARDWARE FAILURE asc:44,84 Vendor Specific ASCQ
, retries:1
sd0(ahc0:6:0): HARDWARE FAILURE asc:44,84 Vendor Specific ASCQ

Has anybody an idea of what is hapening ?

Thanks in advance,
