Re: sparc buildd issues [Re: Release candidate architecture requalification results; amd64 is RC]

I hadn't seen that, thanks. That sunsolve issue is kind of light on the details, but it implies a random drift of a few seconds. The symptoms I see are a sudden forward jump of exactly 3d 6:11:15. Every time it happened I saw exactly the same jump, after which some programs continue running while others hang.

I had a limited ability to track it. The first hang point while trying to log in following the time jump was when running "id -u" in /etc/profile. I determined this by bracketing each section of /etc/profile with echos.

I tried leaving a terminal live and logged in once, but "ps auxww" hung as well. Bind, klog and syslog at least continue running. I suppose the next trick would be to wait for a hang and run them with strace to see which call hangs, but at that point I tried going back to kernel Its been running smoothly since. Whatever the problem is, it doesn't seem to affect .

i'm pretty sure you've seen

where sun says "no workaround"...apparently it's a chip issue that needs
to be worked around in the kernel. bah.
