Hi bugs@, I have a x86_64 7.7 system with a soft raid 1 setup.
I pulled one drive and let it run on the other. I then put another drive in its place to run smart and badblocks test. After being done testing with the one drive, I unplugged it. dmesg didn't show anything about its removal. When I inserted a new drive, I got this panic. tmux locked up. I was able to switch TTYs. I could not login, it would hang after entering my username. Then the panic, which I took a picture of. Sorry about the first letters being obscured. Let me know if you want dmesg or other data with this. Does OpenBSD normally support SATA hotplugging? Thanks! -Henrich
