Fedora 16 kernel panics on HP G70 laptop on any network operation including a ping with kernel 3.2.7-1.fc16.x86_64. With kernel vmlinuz-3.1.0-7.fc16.x86_64 there are no panics, but the firewall doesn't appear to be functional as some allowed operations seem to be blocked. Messages in the log preceding a panic include retry messages for IP6 concluding with "<info> (wlan0): IP6 addrconf timed out or failed".
Steps to Reproduce:
1. Boot system
2. ping (any address) -- or -- any network operation
we need to see the trace from the panic to be able to do anything with this.
what wireless hardware ?

Sample trace from a panic
An item that may be significant that I just noticed in the log for vmlinuz-3.1.0-7.fc16.x86_64, the original kernel, not the one that panics. There is no such message in the log for vmlinuz-3.2.7-1.fc16.x86_64, the kernel that panics
