Problems with the 5.1.14 aic7xxx driver

[Venkatesh Krishnamurthi]

Hi Doug,

  I just updated my 2.2.5 kernel to the 5.1.14 version of the aic7xxx driver.
The driver reports a series of timeouts on boot and then proceeds to use
the Ultra/Wide drives in Async/Wide mode.  I'm attaching the relevant section
from the dmesg output.

  The adapter is a AIC 7890 on a ASUS P2BDS motherboard and the disks are
IBM 9ZX UW.  These worked fine with the driver in the stock 2.2.5 kernel.


Thanks,

Venkatesh
