uvmfault (7.99.1/amd64)
My main machine suddenly hung last night and then rebooted.

One button click pad - I guess that explains why X only recognizes a
single button. The kernel mis-recognizes it. This is a regression, since
in the 6.x kernels it still works fine.
It is also nothing to do with DRMKMS, it also happens in the GENERIC
kernel. X uses the VESA driver there (which is sub-optimal since it uses
a resolution of 1024 x 768 instead of 1600 x 900).

To turn on the checksumming you can run: # ifconfig wm0 ip4csum udp4csum tcp4csum udp6csum tcp6csum Or put the options in you /etc/ifconfig.wm0 file.
