I get the same panic on an IBM xSeries 346 with a ServeRAID-7k
controller (Six 15K RPM 36GB drives, two as RAID1, four as RAID0).  The
panic occurs at random points while sysinstall is copying distributions.
If I do a minimal install, that completes successfully, but then the
same panic occurs while building a new kernel.

5.4-RC1 seems to work fine, but I'm in the same boat as you; my customer
doesn't want to upgrade to RELENG_5 yet.

I'm going to look at backporting the -CURRENT ips driver to RELENG_4,
I'll post patches (and a PR) if I'm successful.
