Colin: I never use sleep mode, all of my normal starting-up/shutting-down works well, but I've never been a fan of sleep mode, so I don't have any good advice for troubleshooting it.
Ivan: Lucid hasn't worked out very well for me, I probably won't try again until closer to release time.
All: I think the very latest kernel may have a fix:

x86/amd-iommu: Fix initialization failure panic
commit 0f764806438d5576ac58898332e5dcf30bb8a679 upstream.
The assumption that acpi_table_parse passes the return value
of the hanlder function to the caller proved wrong
recently. The return value of the handler function is
totally ignored. This makes the initialization code for AMD
IOMMU buggy in a way that could cause a kernel panic on
initialization. This patch fixes the issue in the AMD IOMMU
driver.

I haven't yet tried to compile my own, but I'd love to say that I think that may
be our problem.
