Subject: Re: 2.6.18: Kernel BUG at mm/rmap.c:522
Date: Wed, 11 Oct 2006 11:07:40 -0500 [thread overview]
Message-ID: <20061011160740.GA6868@dingu.igconcepts.com> (raw)
Hi, I can readily reproduce this with 2.6.18 doing 4 simultanous kernel compiles on two disks to load test a P4 3.2 HT with 2GB. I have SMP and SMT scheduling enabled, and the 4GB memory option. Here is output with CONFIG_DEBUG_VM enabled followed by another crash before CONFIG_DEBUG_VM was enabled.
