Using /boot/kernel/kernel, addr2line reports:

    turnstile_head
    ??:0

That doesn't look very useful, so I'll do it again below, after I clean 
things up and make a debug kernel.

I've now reverted back to plain 5.3-R, with just version 1.233 of
ata-all.c added, so that suspend works.

I've done this, and set dumpdev in my rc.conf.

That done, I rebooted and tested suspend/resume.  With the pir0 patch
removed, the resume triggered the ROUTE_INTERRUPT error message three
times, as before.  That was followed by the same panic screen as before,
with these values:

    fault virtual address = 0x0
    instruction pointer   = 0x8:0xc061ed0e
    stack pointer         = 0x10:0xcde52ac8
    frame pointer         = 0x10:0xcde52ac8
    code segment          = base 0x0, limit 0xfffff, type 0x1b

After reboot, I found I needed to symlink /var/crash to a directory with
enough space to hold the core and manually run /etc/rc.d/savecore again.

At this point, addr2line now reports:

    # addr2line -f -e kernel.debug 0xc061ed0e
    turnstile_head
    /usr/src/sys/kern/subr_turnstile.c:763


Since I now have a core file, I expect you'd like to see a backtrace...
(Which is about the extent of my knowledge of gdb.)
