Hi,

Ever since I've upgraded my FreeBSD, the machine will crash during startup displaying a kernel panic fault page which involves the WLAN network driver. I'm able to locate the vmcore.0 file but kgdb isn't able to successfully open the file with the error:
Code:
Cannot access memory at address 0x0
I was in one of the compiled kernel and the command that produce this result was
Code:
kgdb kernel.debug /var/crash/vmcore.0
Crash dump is enabled in the rc.conf file through the following variables
Code:
# Set dumpdev to "AUTO" to enable crash dumps, "NO" to disable
dumpdev="AUTO"
dumpdir="/var/crash"
I want to discuss this further if people have the time.

Thanks.
