It turns out some errors will turn up in memtest86+ if you select 'Bios Probe' as the sizing method. Otherwise using the e820 method by default it will run all day over the 10G. The Memtest doc themselve state that 'Probe' and 'All' may return the same sizing and are not considered safe. 'Probe' seems to behave exactly the way -current is behaving (returning errors, and reseting the box). 'All' happens to lock the box on this machine. Since I can go back to the Oct 15th kernel and do a complete buildworld, I can only assume -current has changed since then for amd64 sizing to maybe access something other than what the e820 method would return? The SMAP appears the same, but you can see the difference in the Physical memory chunk(s) below for the two kernels. 8-current (from Feb 4th): SMAP type=01 base=0000000000000000 len=000000000009f400 SMAP type=02 base=000000000009f400 len=0000000000000c00 SMAP type=02 base=00000000000f0000 len=0000000000010000 SMAP type=01 base=0000000000100000 len=000000000ff00000 SMAP type=01 base=0000000010000000 len=0000000010000000 SMAP type=01 base=0000000020000000 len=00000000afe4e000 SMAP type=03 base=00000000cfe4e000 len=0000000000008000 SMAP type=01 base=00000000cfe56000 len=0000000000001000 SMAP type=02 base=00000000cfe57000 len=00000000001a9000 SMAP type=02 base=00000000d0000000 len=0000000010000000 SMAP type=02 base=00000000fec00000 len=0000000000100000 SMAP type=02 base=00000000fee00000 len=0000000000010000 SMAP type=02 base=00000000ffc00000 len=0000000000400000 SMAP type=01 base=0000000100000000 len=00000001affff000 usable memory = 10720202752 (10223 MB) Physical memory chunk(s): 0x0000000000001000 - 0x000000000009bfff, 634880 bytes (155 pages) 0x0000000000f54000 - 0x00000000cfe4dfff, 3471810560 bytes (847610 pages) 0x00000000cfe56000 - 0x00000000cfe56fff, 4096 bytes (1 pages) 0x0000000100000000 - 0x000000029d212fff, 6931165184 bytes (1692179 pages) avail memory = 10365558784 (9885 MB) 8-current (Oct 15th) SMAP type=01 base=0000000000000000 len=000000000009f400 SMAP type=02 base=000000000009f400 len=0000000000000c00 SMAP type=02 base=00000000000f0000 len=0000000000010000 SMAP type=01 base=0000000000100000 len=000000000ff00000 SMAP type=01 base=0000000010000000 len=0000000010000000 SMAP type=01 base=0000000020000000 len=00000000afe4e000 SMAP type=03 base=00000000cfe4e000 len=0000000000008000 SMAP type=01 base=00000000cfe56000 len=0000000000001000 SMAP type=02 base=00000000cfe57000 len=00000000001a9000 SMAP type=02 base=00000000d0000000 len=0000000010000000 SMAP type=02 base=00000000fec00000 len=0000000000100000 SMAP type=02 base=00000000fee00000 len=0000000000010000 SMAP type=02 base=00000000ffc00000 len=0000000000400000 SMAP type=01 base=0000000100000000 len=00000001affff000 usable memory = 10720538624 (10223 MB) Physical memory chunk(s): 0x0000000000001000 - 0x000000000009bfff, 634880 bytes (155 pages) 0x0000000000f02000 - 0x00000000cfe4dfff, 3472146432 bytes (847692 pages) 0x00000000cfe56000 - 0x00000000cfe56fff, 4096 bytes (1 pages) 0x0000000100000000 - 0x000000029d212fff, 6931165184 bytes (1692179 pages) avail memory = 10365890560 (9885 MB) -- Mark Atkinson atkin901_at_yahoo.com (!wired)?(coffee++):(wired);Received on Mon Feb 09 2009 - 21:50:22 UTC
