I just posted a followup comment on bug # 405... what are you using
for a
motherboard?
I use Tyan S881 and S882 motherboards.
My mistake, S2882. Link: http://www.tyan.com/products/html/thunderk8sr.html
I'm not getting any hits on google for "Tyan S881" ... ahh, s4881 and
s4882 ... that 4 makes a difference :)
hhmm, looks like that will likely have the same fragmented memory layout
that the supermicro's have, as each processor has locally attached
memory.
ever tried to boot one of these without a 64bit or pae kernel? Does it
only see 1/4 of the memory? what does the boot time memory map look like?
e.g. (from dmesg)
BIOS-provided physical RAM map:
BIOS-e820: 0000000000000000 - 000000000009fc00 (usable)
BIOS-e820: 000000000009fc00 - 00000000000a0000 (reserved)
BIOS-e820: 00000000000e8000 - 0000000000100000 (reserved)
BIOS-e820: 0000000000100000 - 00000000bfff0000 (usable)
BIOS-e820: 00000000bfff0000 - 00000000bffff000 (ACPI data)
BIOS-e820: 00000000bffff000 - 00000000c0000000 (ACPI NVS)
BIOS-e820: 00000000ff780000 - 0000000100000000 (reserved)
BIOS-e820: 0000000100000000 - 0000000140000000 (usable)
My second memory bank starts at 0x0000000100000000, which is 2^32
(4gig)
I have posted another panic to bug #402. I have everything so if Ian or
another developer wants more info I have the vmlinux/System.map/config
available.
My board shows:
BIOS-provided physical RAM map:
Xen: 0000000000000000 - 0000000020000000 (usable)
Here is the physical RAM map under xm dmesg:
