Bug #2570: commit 79ce07d03a6... Improve pageout daemon for tmpfs causes reboot 
running Firefox

commit 79ce07d03a6... "Improve pageout daemon for tmpfs write load" has been 
bisected on two machines running 3.5-DEVELOPMENT, one an Intel-based machine 
running x86_64 and the other an AMD-based machine running i386, as inducing a 
reboot seconds after starting Firefox or other applications such as the pkgsrc 
0.17 Enlightenment desktop.  Reboots have been induced either running current 
pkgsrc Firefox or dports Firefox.  Both machines are using Radeon 4xxx graphics 
cards and both have set in /boot/loader.conf
vma.dma_reserved=67108864.
Updates through commit 3ec72a5566c2c0... "Change lwkt_wait_ipiq() to use the 
TSC" do not prevent manifestation of the panic.

Attached is a core.txt file retrieved from /var/crash after a reboot.
