Obviously, you'll fail. >Fix: In /usr/src/sys/dev/aic7xxx/aic79xx_pci.c, line 69: #define ID_9005_GENERIC_MASK 0xFFF0FFFF00000000ull this line breaks successful AIC-7902 detection with HostRAID option turned on because it reports itself as another device ID (809F vs. 801F with disabled HostRAID). So change the mask to be 0xFF70FFFF00000000ull (don't care about the specified bit) and thus the detection problem is solved. BEWARE: while our HostRAID has been configured for mirroring, both disks were seen by FreeBSD (da0 and da1), so maybe different communication method should be used. I failed to find any contact addresses of driver developer from Adaptec, so I can't verify that. >Release-Note: >Audit-Trail: >Unformatted:
