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

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

I can confirm this. Probably it's related only to wireless connections, wired seems be OK. My device is:

Mine is a wired connection, so it seems unconnected with that. I've replaced the motherboard here and have had no further problems. There is now a configuration difference though as I've had to disable radeon kms (with radeon.modeset=0) for the new on-board graphics.

My guess is that this is radeon related, and I'm going to set-up the old motherboard in a spare case & see what I can work out.

I'm not sure. I don't use radeon hardware, only Intel:
cat /boot/config-2.6.33-rc2 | grep -i radeon # CONFIG_DRM_RADEON is not set
# CONFIG_FB_RADEON is not set

cat /boot/config-2.6.33-rc2 | grep -i kms
CONFIG_DRM_KMS_HELPER=m
# CONFIG_DRM_I915_KMS is not set

The mystery deepens :-) Maybe these are separate issues?
