Hello.
Trying to play around a bit with softraid using vnd reliably results
in a panic when assembling the raid volume. I think the first time I
tried this was around 4.9 so it's not something new.
While the combination of vnd and softraid may not be useful for any
real purpose, I noticed this while hoping to be able to fail a disk in
a somewhat simpler to retry manner than the nailgun approach I read
about here recently...
I don't know if it's important, but also after the trace and ps listed
below, boot reboot won't reboot the first time, but I can enter ddb
again by sending a serial break and then get the machine to reboot by
reexecuting the boot reboot command.
Regards,
Eivind
