Subject: [2.6.36-rc regression] occasional complete system hangs on sparc64 SMP
Date: Thu, 23 Sep 2010 19:02:22 +0200 [thread overview]
Message-ID: <19611.34846.813757.309183@pilspetsen.it.uu.se> (raw)
On my Sun Blade 2500 (2 CPUs), post 2.6.35 kernels sometimes hang
completely without visible messages on either the console or in
the kernel logs.
The first two times (with -rc1 or -rc3) it happended during gcc
bootstraps + regression test runs, today (with -rc4) it happended
while compiling the 2.6.36-rc5 kernel. It's very sporadic, perhaps
one of ten boots will eventually hang like this.
With 2.6.35 the machine is rock solid.
The 2.6.36-rc kernels do appear to be solid on a UP Ultra5, but that
one no longer does any gcc builds or tests, only kernel builds.
Any ideas, or do I have to try to bisect this?
