Strange problem from 2.4.9 to 2.4.20

Strange problem from 2.4.9 to 2.4.20

[Nicolas Bouthors]

Hi all,

I hope this is not a FAQ, I tried to look in the archives but couldn't 
find anything relevant :
I have a problem with a change of kernel. The machine is a dell with 2 
internal SCSI
drives and an external RAID array the machine has 4 Adaptec controlers 
and evetything
works fine with kernel 2.4.9 from Redhat. For testing purpose I compiled 
a 2.4.20 and
when I boot I get the following message :

(scsi2:A:3): 80.000MB/s transfers (40.000MHz DT, offset 31, 16bit)
(scsi2:A:3:0): parity error detected in Command phase. SEQADDR(0x1a2) 
SCSIRATE(0xc3)
  CRC Value Mismatch
  No terminal CRC packet recevied
  Illegal CRC packet request
  Unexpected non-DT Data Phase
scsi2:A:3: Missed busfree. Lastphase = 0xe0, Curphase = 0x0
(scsi2:A:3:0): parity error detected in Command phase. SEQADDR(0x1a2) 
SCSIRATE(0xc3)
  CRC Value Mismatch
  No terminal CRC packet recevied
  Illegal CRC packet request
  Unexpected non-DT Data Phase
scsi2:A:3: Missed busfree. Lastphase = 0xe0, Curphase = 0x0

sdc should be the external RAID array but it is not seed by Linux after 
this message and not usable.

The rest of dmesg is normal, except for this part and the hardware 
configuration didn't change,
only the kernel.

Any comment apreciated,

Thanks,
