HEADS-UP: PCI ID driver conflict with ahd(4) and pms(4)

[Glen Barber]

The new driver for PMC Sierra SAS/SATA HBAs does not properly validate
that both the vendor ID and device ID of some storage device drivers.
At present, we know there is a conflict with ahd(4), it is possible
there are more.

The issue was reported on the -current@ mailing list in this thread:

If you are running 10.2-RC1, you should be unaffected when upgrading to
10.2-RC2.  If you are running 10.2-BETA2 or prior (and 10.2-PRERELEASE
prior to the releng/10.2 branch), please exercise caution when upgrading
to the latest stable/10 or releng/10.2 if your storage controller
matches any of the following PCI device IDs:

 0x0100
 0x0101
 0x0102
 0x0103
 0x0104
 0x0105
 0x0110
 0x050A
 0x1028
 0x1029
 0x102a
 0x1200

 0x8088
 0x8089
 0x8091
 0x8098
 0x8099
 0xB555
 0xabcd

The resolution to this issue is still being investigated, and is
considered a blocker for the 10.2-RELEASE, which means it is now quite
likely there will be an -RC3 for this release.

Thank you for your patience while this issue is being resolved.
