Hi all,
I get a "Segmentation fault (core dumped)" on my system using ntpd.
I checked the archives, and there is one messeage about something like
this on a 405.
Is anybody working on this ? Did I missed some patches ?
cheers & thanks

If you clock is sufficiently out of date.. (I.e. 50/60 more? years
wrong) then you can get into an overflow situation. While I've never
seen it segv, I have seen it do other 'interesting' things.
Try setting your clock to Jan 1 2000, then run ntpd and see what happens.

Dear Emanuel,

This is caused by some (I2C based RTC's in "11 minute mode".

We fixed this by making this mode configurable (and disable it by
default) in our version of the linuxppc_2_4_devel tree; the patch was
added on May 29, so just "cvs update" your source tree.
Best regards,
Wolfgang Denk

No idea, but if you're using ELDK binaries, you might check
with their mailing list.
And then there's always compiling ntpd yourself and running
it under gdb or gdbserver to see where it's crashing...

I checked that already ;-)
I set the clock manually before that, and the difference between the
server and the local clock was less than a minute.

Sorry Wolfgang,
this one is a STMicro M48T86 (ds12887 compatible), and is sitting on the
local bus ...

I have to check again, but the kernel was made on july 15. And usually I
update my sources before build. But I check again ...
Thanks,
emanuel

Is ntpd trying to update your RTC out on i2c in interrupt context?
