This is on a Dell PowerEdge 1850 with PERC 4e/Si which uses ami(4).
bioctl works fine on 4.9. The problem appears to be kernel-side, as:
* booting a 4.9 ramdisk, then mounting/chrooting into my 5.0 install:
bioctl works
* booting the latest snapshot bsd.mp (but not modifiying userland):
bioctl works
Also, when upgrading from 4.9 to 5.0 (via bsd.rd), it had a similar
panic at the end of the upgrade procedure (the last thing printed was
the MAKEDEV step). I haven't had any panics since then aside from
those caused by bioctl, but the system hasn't been under much load.
It looks like some post-5.0 fixes went into sys/dev/ic/ami.c which
fixed this problem. Can an erratum be issued for this?
Panic output (happens after running 'bioctl sd0', every time):
