No, the problem is not in the BIOS, it is in the kernel and it is
described at length in the upstream bug report. If I understand this
description correctly, the kernel is not compliant with the ACPI
specification in that it handles all ACPI events in a single thread,
whereas the ACPI spec only says that the *interpreter* must be
single-threaded. Also, there is a deadlock situation in the kernel
which is clearly a kernel, not BIOS, bug.
