 And I just did, I grabbed NetBSD 10.0_BETA i386 boot iso from:
 
 http://nycdn.netbsd.org/pub/NetBSD-daily/netbsd-10/202310212330Z/i386/installation/cdrom/boot.iso
 
 and installed it on another one of those Alix machines I've got kicking
 around. Somewhat similar behaviour. I can do a few sessions with cu
 (3-5 seems to be typical) and then, with the next session, cu just hangs
 (sitting in status D, no output and so far I've been willing to wait a few
 min but to no avail).

 and again, nothing in dmesg.

 Kind regards,
