2.6.33-rc1 - Weird hard hangs when rendering 'some' web-sites inFirefox

[David]

I'm still not sure whether what I'm seeing here is latent hardware
problems, but, as a heads up :-

    2.6.32, 2.6.32.2 (and previous kernels) - All OK
    2.6.33-rc1 - Machine seems fine, until :-

I browse to particular sites (one of which is an internet banking site,
so no heavy flash etc.). My machine will (completely and repeatably)
hang solid. Nothing showing with netconsole, sshd dead, sysrq dead ...
reset button time.

.config, bootup dmesg, and lspci -vvv attached for interest (userspace
is Ubuntu 9.10).

May have time to bisect, but not 'till the holidays.

Cheers
David
