Some IBM systems either hang or panic after install. The following panic message is displayed:
Unrecoverable Machine-Check Exception |
Workaround 1: Add the following line to the /etc/system file after installation to avoid system hang:
set pcie:pcie_aer_ce_mask=0x11C1 |
Workaround 2: If the system panics during install or during boot after the install, then use this workaround. Boot the system, with -kd option and set it in the kmdb debugger:
::bp pcie`pcie_initchild :c pcie_aer_ce_mask/W 11C1 :d all :c |
When the system comes up append the following line to the /etc/system file to make the changes permanent:
set pcie:pcie_aer_ce_mask=0x11C1 |
