Hi..
My kernel (2.6.35) gets stuck at boot, as dmesg documents:
....
[ 0.006590] ACPI: Core revision 20100121
[ 45.278951] DMAR: Host address width 36
...
Setting acpi debugging to give-me-all-you-can produces ~120Mb dump.
The interesting part appears to be:
.....

.....
So....
What is happening here and whose fault is it?
Is it a Linux kernel or ACPI firmware problem?
Thanks for any pointers,
Martin
