I recently changed the my MacBook's hard drive since my MacBook kept restarting. Now there's another problem.
Whenever i leave the MacBook on (using wifi) and come back the internet would be disconnected. Then when i click the AirPort button a message telling me to Restart The MacBook comes up.
So, i do restart the MacBook, and when it's back there will be a message saying "MacOS X quit unexpectedly".
This is the Problem Report Details:
panic(cpu 1 caller 0x0039CD77): "m_free: freeing an already freed mbuf"@/SourceCache/xnu/xnu-1228.0.2/bsd/kern/uipc_mbuf.c:2742

Looks like airport driver issues. What wifi hardware (router model, brand) are you using?

The error message looks very similar to the ones reported in the Apple Support Forums. One application notorious for causing this is Azureus. Are you using such an app? Turning off IPv6 / Link-Layer tends to help sometimes, but isn't always the cure. Others have switched fromto alternate apps (e.g. Transmission) until Apple works out the issue.
