>Description:
if_igb driver panics during bootup.
The IGB driver probes the device at line 591 of if_igb.c and punts:
if (e1000_validate_nvm_checksum(&adapter->hw) < 0) {
device_printf(dev,
"The EEPROM Checksum Is Not Valid\n");
error = EIO;
goto err_late;
}
The kernel immediately panics with a page fault. The trace-back show it's in the if_igb driver as the console messages suggest.
Releng_8 did not panic, so this is a regression. The IGB NIC most likely has some sort of problem which is properly diagnosed.
Email me if you want the screen shot of the panic, or have a fix to try out.
>How-To-Repeat:
Crashes every time on boot.
>Fix:
Disabled compile of if_igb.c driver, system boots fine.
