| |
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?
