i run debian lenny for amd64 on my HP 6715b with 4Gig of RAM. When i try to
hibernate my machine i became the error:
"Some devices failed to power down"
I also found
"Class suspend failed for gart0"
On boot time the linux kernel 2.6.26 says, that i should activate IOMMU on the
BIOS. But i can't because the BIOS doesn't has such an option. When i take
2Gig of RAM out of my computer, the hibernate process works fine.
How can i bring my HP 6715b to hibernate with the full 4Gig of RAM? Any
chance, hint, suggestion, what ever?
