Since this is my first post on this list, I would like to say hello to
everyone!
I am experiencing problems with a 2x dual core opteron servers. every
5-7 days the system hangs. while it still pings, it does not react on
console inputs, i can't login via ssh either. when that happens, the
only thing one can do is to reset the machine. there aren't any errors
logged.
i have checked the memory for errors, but it looks like it is ok.
I found a post on this list describing a problem which looks similar to
mine:
http://www.gatago.com/linux/kernel/13699679.html
as mentioned in the above post, a dmesg on my server also shows
following entries:
Allocating PCI resources starting at fb800000 (gap: fb000000:4780000)
Checking aperture...
CPU 0: aperture @ cc24000000 size 32 MB
Aperture from northbridge cpu 0 too small (32 MB)
No AGP bridge found
Your BIOS doesn't leave a aperture memory hole
Please enable the IOMMU option in the BIOS setup
This costs you 64 MB of RAM
Mapping aperture over 65536 KB of RAM @ 8000000

can those entries have anything to do with the system crashes, and if,
can booting with iommu=memaper=3 help to solve the problem?
i am running kernel 2.6.17.11, sarge amd64 , the system has 6GB RAM
i appreciate any suggestions :)
