kw; cat /dev/cputype
ARM Marvell 88F6281 A0; arm926ej-s arch v5te rev 2.1 part 131 1200

1.  timesync locks up my machine.  i have the latest clock.c
i'm using
	aux/timesync -nl -d /sys/log/timesync.d -a 100000 $timeserver
perhaps there's something wrong with that?

2.  initially crashed on nvram prompt due to kbdq being nil.
"fixed" by initializing it.

however, geoff claimed a fix in december.

I'm running timesync here on a sheevaplug and an openrd-client.
The invocation was

	aux/timesync -s /net -nl -d /sys/log/timesync.d chips time1 time2

100 µs accuracy seems unlikely; you might try dropping the
`-a 100000' from your invocation.

The kbdq business is almost certainly a result of difficulty
getting the uart machinery to work properly; I ought to revisit
that stuff.

ah, yes.  thanks for the reply.  i'd figured that out today.  i'm
sending this from a drawterm to the openrd.  :-)

on that note, do you think that using tftp to download
/cfg/pxe/$ea from the kernel would be a bad idea?  do you
have an alternate idea for downloading a bit of configuration?
i'm thinking of doing something soon.

i was thinking that perhaps timesync should refuse to run if the
accuracy is unreasonable?
