[Please keep me on Cc, I am only subscribed to linux-kernel] Hi Bagas, thanks for your quick answer.

Without having read the docs (that came too late, need to read up on that again), my bisect came out at 84a9582fd203063cd4d301204971ff2cd8327f1a being the first bad commit. This is a rather big one, that does not easily back out of the 6.5 release. Sadly, just transplanting drivers/tty/serial from a 6.4.12 tree doesn't even build. I'm adding Tony Lindgren, the author of the commit, to the Cc list. But, since the commit is related to serial port, I began fiddling around with the serial port setting on the misbehaving VM and found out that running the VM without the serial console that I am using (thus removing "console=ttyS0,57600n8" from the kernel command line) makes the machine boot up just fine with the 6.5 kernel that I built yesterday. It is not even necessary to remove the virtual serial port. The issue is still somehow connected to the host the machine is running on, since my VMs all have a serial console and the test VMs running on different hosts are running fine with 6.5.
