Just my experiences with 1.3.68, perhaps somebody can make use of this.
First time I booted it it hung when I wanted to shut down the system: It was
in the "killing all processes" phase when the following message appeared on
the screen and a second time after some time: Socket destroy delayed
After that nothing happened, I couldn't stop the shutdown from the
console, I could still ping the machine but not telnet into it (probably
inetd was not running) - but it didn't finish shutdown either (at least
not in about 20 minutes, when I pressed the reset button).
OK, so much for that, I couldn't reproduce this. I have 1.3.68 now
running for 12 hours with pretty heavy load and no visible problems so far,
everything works fine, networking too.
But inspecting the dmesg output shows this:
scsi1: REQ before WAIT DISCONNECT IID

What do these mean? I have not seen the missed interrupt and
INTFLY messages before, the REQ before WAIT were already there
in 1.3.59
Rest of dmesg so you see the system configuration:
