>Description:
Using a Tyan Tempest II (S1462) MB, upon booting up a 3.4-stable (or 4.0-release
for that matter) kernel, I get the following error messages:

Data Parity Error detected during address or write data phase
(probe14:ahc1:0:0:0) SCB 0xe timed out while idle, SEQADDR == 0x159
Queuing BDR SCB

Both of these messages are duplicated one for ahc1 and ahc2. The S1462 MB is a combo EISA/PCI
MB. ahc0 is an adaptec 1742 controller (eisa).
>How-To-Repeat:
Boot with card installed
>Fix:
This might be a bad 3950U2 controller card but it could be a motherboard incompatibility or a software
issue.

                              ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 That would be impressive since the driver for the 174x card is 'ahb'.
 
 Do you mean 2742?

 opps. yes, 2742.

State-Changed-When: Mon Aug 15 13:04:49 GMT 2005 
State-Changed-Why:  
These errors are caused by some other bus master on the PCI bus 
incorrectly setting parity on its bus transactions.  If the parity 
failure occurs on an address frame, the ahc device cannot determine 
if the transaction was for it or someone else, so the driver complains. 
Recent versions of the driver have been altered to only complain a 
few times before disabling the check for these failures so that a 
system that chronically experiences pci parity errors is not flooded 
with messages.
