Public bug reported:
My system is a newly build Ryzen 3600 based system with Vega 56
graphics.
On suspend wakeup, the entire system locks up. A workaround is booting
with linux kernel version 4.19.69.
Using newer linux versions (5.3-rc7) did not fix the issue.
The motherboard is an MSI B450I gaming plus ac board; I've loaded up
both the official non-beta BIOS (7A40vA8) and the newest beta BIOS
(7A40vA91) and both have this issue.
No dmesg logs are available after the suspend wakeup (last message is
putting the system to sleep)
I have a r8169 and iwlwifi based ethernet and wifi cards, but I've
tentatively isolated that those two are not an issue by blacklisting the
respective modules.
