Yup. The seek failed indicates it wasn't able to read something it needed to read. So the next step is to do the above, only instead of calling mount-root, figure out what mount-root has in it, and execute those one-by-one at the ok prompt. Or use the debugger to single step through it.
Here's that output:

So, I added debug for "$open-package" which led to "open-package", which I also debugged - here's the output from mount-root after turning on all that debugging:

Based on that output, it's hard for me to tell what about "open-package'" failed
Somewhere in there either you are coming up with some bad disk addresses, or the HBA driver is failing a read. The alternative would be to debug the HBA driver and see what disk reads you are being asked to do, and try to trace backwards.
I'm already headed down this path, so I'll stick there, now, unless you have some hints for going about debugging the HBA driver, which I would assume I would do from the Qemu source code side...

Yup. What I spot:
: mount-root ( Empty ) 00000000ffe35d28: boot-dev$ ( ffe357a8 6 ) 00000000ffe35d30: fs-pkg$ ( ffe357a8 6 ffe317c0 10 ) 00000000ffe35d38: $open-package : $open-package ( ffe357a8 6 ffe317c0 10 )
It looks like fs-pkg$ names the package it's opening. I'm guessing that's hsfs-file-system, but you should probably verify that's what is in that string (do a "2dup type" before calling $open-package). If that's correct, then rather than descending into open-package, you probably want to put a breakpoint at "open" in /packages/hsfs-file-system, which is where that will end up after much wandering around. Then proceed from there - you really don't want to trace through instance creation.
The reason you weren't able to see all that (which would have been overwhelming) is a bit further down:
00000000ffe135f0: (lit) ( 1 ffe2fe38 ffe4b1d8 ffe4b548 ffe135e0 4 ffe4b558 ffe13310 ) 00000000ffe13600: catch ( 1 ffe2fe38 ffe4b1d8 ffe4b548 ffffffffffffffff 0 )
That's basically a subroutine call to ffe13310, which it didn't show.
Oops. That wasn't very readable. I'm not sure what happened. Trying again:
