Hi,
I'm bisecting a boot freeze with 4.10-rc2 on a laptop and the commit in
$Subject is introducing a breakage, see attached splat. Unfortunately,
it is not complete as I don't have any other means of logging dmesg on a
laptop.
A temporary workaround is to boot with "intremap=off".
Unfortunately, I cannot revert
174cc7187e6f ("ACPICA: Tables: Back port acpi_get_table_with_size() and early_acpi_os_unmap_memory() from Linux kernel")
as it doesn't revert cleanly anymore. From looking at the callstack,
though, it looks like AMD IOMMU is calling acpi_put_table() and patch in
$Subject touches it so I'm guessing the AMD IOMMU needs to be updated to
the new way of parsing the IRQ remapping tables or whatever is going on
there - I'm just guessing.
Hi,
Please check if this helps:
