Re: 2.6.0 test3 does not boot on ia64 NUMA

Martin,

Thanks for the information (Until now CONFIG_DISCONTIGMEM was
exclusive with CONFIG_VIRTUAL_MEM_MAP).

System now builds OK with Jesse's patch + the acpi alloc_bootmem patch.

Unfortunately, it dies somewhere after entering paging_init(), and before
printing "On node %d totalpages:":

ifa=0xf000ff54f7c5722b
iip=0xa0000001007780d0
0xa0000001007780d0 <__alloc_bootmem_core+592>:	[MII]       ld8 r17=[r19],8

last traces are:

Mca related initilaization done
kernel unaligned access to 0xf000ff54f000eefb ip=0xa0000001007780d0
kernel unaligned access to 0xf000ff54f000ef03 ip=0xa0000001007780d0
kernel unaligned access to 0xf000ff54f000ef0b ip=0xa0000001007780d0


I will try to look at this a bit more if I find some more time.

Thanks again.

Xavier
