I think KiBi got bitten by the bug described in the commit message for
4efbcf, where the next packet would be discarded as packet_discard() ended
up being called twice for some codepath.
However I have a hard time believing that commit did fix the issue
reliably for KiBi's setup. If it did, I believe I wouldn't have had any
problems in my setup.

He told me he'd try it out next week and report back. In the meantime, I
have the patched ipconfig in production and it's working even better than
1.5.12 did, so I'm really confident those patches fix ipconfig for good.
Actually we haven't had a single failure with that patched version and
interface configuration happens immediately.

You're welcome. Just to make sure, both patches are needed. Even with the
second patch applied, there are still cases where the interface can go
into DEVST_ERROR and enter an infinite loop due to this missing case in
the first switch() statement. I think it would mostly happen on machines
with more than one interface when running ipconfig on all interfaces. It
falls in the "obviously correct even if unneeded" category, anyway.
