Hi Doug!
We have a Adaptec 3985W (PCI_DEVICE_ID_ADAPTEC_7873) board with 9 4.5Gb
disks, 3 on each channel -
and were still running linux-2.0.33/aic7xxx-4.1.1 -
Now did upgrade to 2.2.12 with aic7xxx-5.1.19:
After lots of problems I looked into the old driver from 2.0.33 and saw:
The external SCB RAM on the 3985W does not work and was disabled by
#ifdef AIC7XXX_USE_EXT_SCBRAM.
With the following patch to linux-2.2.12/aic7xxx.c-5.1.19 everything works
fine.
Maybe this is needed only for
temp_p->device_id == PCI_DEVICE_ID_ADAPTEC_7873.
