Subject: usb regression on armv7 after upgrade to 7.0

Hi all,
While trying to test 7.0 on a bunch of machines, I upgraded my armv7
machine (a CuBox) that I use for console access to my home router.
There's a uplcom(4) that stopped working after upgrading to the latest
snapshot:
cu: open("/dev/cuaU0"): Input/output error
After downgrading the kernel to 6.9, I can open cuaU0 without an issue
again.
Things worked fine with
OpenBSD 7.0-beta (GENERIC) #80398: Thu Aug 26 13:18:27 MDT 2021
Things broke with
OpenBSD 7.0 (GENERIC) #80403: Sun Sep 19 00:05:48 MDT 2021
And I'm now back to
OpenBSD 6.9 (GENERIC) #386: Tue Apr 20 04:06:48 MDT 2021
dmesg for #80398 and #80403 are below, but at least I see no obvious
difference that would explain the change in behaviour there.
As this is very slow and space constrained machine, does anyone have
any candidates to try to revert? Looking at source-changes since
August 25, I see a bunch of commits to ucc(4), some to dwctwo(4), the
addition of uaq(4) but nothing really seems to be relevant for this
issue.
Any suggestions?
Paul
