I run FreeBSD 11-STABLE on actual machines, and I build the system every few days. Things have been fine.
However, I also run FreeBSD 11 via the qemu emulator on my Mac. I run lots of different BSD & Linux OSes here to test them out. I have been running the same binary of qemu-system-x86_64 v1.2 for six years. It runs great.
Then recently this happened:
This snapshot dated 20180329, after doing a fresh install, runs fine:
I can run pkg install and begin adding stuff to the system and life is good.
This snapshot dated 20180408, after doing a fresh install, will crash when running pkg install:
It crashes about 90% of the way through updating the pkg snapshot. It does not matter what pkg you try and install.
However, the latest release in the i386 flavor works fine on qemu:
So sometime between March 29th & April 8th, in amd64 boot code, I believe the problem was introduced.
I cannot debug the crash, because it does a kernel dump, and then when the system reboots, almost anything again triggers a kernel crash and it reboots again and again: no chance to inspect a mini dump or whatever.
I wish I had more to go on, but I am happy to off list work with anyone that wants to pursue this, by testing out stuff or answering more questions.
Running FreeBSD since 2.2.8
