Hi Wei,
A Debian user has hit this message and reported it in
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=684661
I think it is the BUG_ON in:
struct amd_iommu *find_iommu_for_device(int bdf)
{
BUG_ON ( bdf >= ivrs_bdf_entries );
return ivrs_mappings[bdf].iommu;
}
It looks like ivrs_bdf_entries comes from ACPI. Unfortunately the bug
report is a bit vague about things like stack traces etc so it's hard to
say where BDF came from.
Any ideas? I'll also follow up to the submitter to try and get some more
details.
Ian.
