8.0-R/amd64 problems with Dell DRAC4 (8th Gen)

[Brian A. Seklecki]

All:

   6 years out, it looks like cd(4)/ata(4) still has problems
   reading virtual CD media in the Dell PowerEdge DRAC4 LOM.

   We see ~ 30x of these in dmesg:
   acd1: WARNING - READ_TOC read data overrun 20>12

   Followed by this in sysinstall:

   "The disc in your drive looks more like an audio disc than a
   FreeBSD Release" (1).

   acd1: DVR <VIRTUALCDROM DRIVE/> at ata2-slave PIO3
   acd0: CDROM <TEAC CD-ROM CD-224E/K.9A>

Of course, the BIOS is able to read from the disc and load mfsroot. 
Maybe a sysctl tweak is needed at loader(8).

It just seem like, given the market penetration of PowerEdge 8th gen, 
this would be behind us.

Latest DRAC firmware.
