Yes. Based on latest dmesg, the ACPI tables contain code which schedules
the worker and takes so long. It is possible / likely that his board
contains the same tables which leads to the same effect. After all those
two boards are very similar from the naming part :)
Would you mind to dump the ACPI tables and send them? There might be
some hints.

It might be possible that a BIOS update fixes the problem but I would
prefer very much to fix this in kernel to ensure that such a BIOS does
not lead to this problem again.
