BIOS Settings—Operating System Hangs or Goes into KDB Mode
When a single bit error occurs in the memory of a server, it causes the Linux OS to lock up, which puts
the server into kernel debugger (KDB) mode. This is because of the BIOS Error Correcting Code (ECC)
Type being set incorrectly.
To correct the ECC Error Type setting in the BIOS Setup Utility, do the following.
Step 1 During the server bootup, press the Delete key to enter the BIOS Setup Utility.
Step 2 Navigate to the Advanced menu and choose Advanced Chipset Control.
Step 3 Choose ECC Error Type and change the setting to NMI (Figure A-2).
