(In reply to Mariusz Zaborski from comment #3)

I hit this bug as well, trying to resize da0p2 of a secondary disk that has 3
partitions.
Maybe I could answer your questions to help reproduce the error.

- What is your root? (It was da3p5?)
# my root is on another disk

- Was da3p5 mounted?
# the partition I tried to resize wasn't mounted

- da3p5 was clean or there was a UFS there? (Did you do newfs before resize?)
# newfs was ran on all the partitions on this disk before resize (freebsd-ufs)

- How much data you had on da3p5?
# the resize partition is new and empty with 50G of space

$ sudo gpart resize -i 2 -a 1M -s 25G da0

After kernel panic and rebooted manually, gpart in my case is showing resize
was completed.

gpart show da0
=>       40  625142368  da0  GPT  (298G)

I hope this helps.
