Subject: [PATCH 1/2] boot: increase stack size for kernel boot loader decompressor
Date: Tue, 25 Mar 2008 18:41:38 -0700 [thread overview]
Message-ID: <20080326014138.134849000@polaris-admin.engr.sgi.com> (raw)

Increase stack size for the kernel bootloader decompressor. This is
needed to boot a kernel with NR_CPUS = 4096. I tested with 8k stack
size but that wasn't sufficient.
Based on:
