I (still) have the same problem on my MSI Platinum .... and having re-read
all of those threads in case I missed somehting, there still isn't a
solution there. All the suggested ones (using 'Linux" as ACPI name, moving
com interrupt ports, disabling onboard ether) are reported as failing
after a few days. Luckily I have a colleague who can reboot the remote
machine, and that has been my solution - but it is not really workable
long term.

(actually this has reminded me to check dmesg, and it seems I need to
reboot this machine due to an interrupt storm right now).
