Description Don Zickus 2011-08-30 16:09:56 UTC
Description of problem:
When the code to enable the APEI bit in the firmware was pushed upstream, it forgot to actually set the bit to enabled.  Instead it just told the firmware that it modified it.  Most firmware didn't check to see if this modification was to enable or disable APEI, so everything worked fine.

However, Dell noticed their boxes were not working and it was because their firmware actually did the right thing and checked to see if the bit was enabled or not.  And it wasn't.

Matthew pushed a patch upstream to actually enable the bit.  This is needed for 6.2 because our customers who wanted APEI need to have this set otherwise APEI won't work.

It can easily be verified on various recent Dell boxes by running the error injection tests.
