I have a T60 running with 2.6.34.1 using your config and so far no issues. 

Looking at your lspci output - your system has a slightly different HW, but I don't know if this is significant.

Are you loading the kernel with any parameters (cat /proc/cmdline)?

Do you have firewall configured (iptables -L)?

Also now that 2.6.35 is out - could you give it a try and see if the situation had improved?
