- Mixing of memory widths appears to cause memory errors. The 256MB and 64MB DIMM from the table below show memory errors when installed together. Single-row memory might also be a problem, as the 128M single-row module gives errors. Double-row memory might also be a problem, as the 256M gives errors.
- shutting down system does not turn off power.
- Hangs at ram detection. Patch available 2007-06-04
- MA map type is set incorrectly for some types of DIMM. Fixed as of r2653.
MA Map Types
The values for MA map type refer to bits 15-13, 7-5, and 3-1 of offset 0x59-0x58 of the VT8601A host bridge. See the VT8601/PLE133 data sheet for details. All values other than 0xx and 100 are documented as "reserved (do not program)"
