I can not access the 455516 bug.
Comment 4 John Villalovos 2008-07-25 09:29:21 EDT
This bug almost seems like a dupe of #428909 since the same patch solves both
issues.
Comment 5 Peter Martuccelli 2008-07-25 09:49:06 EDT
Build a brew kernel with the patch and have people test against bug 428909.  I
will mark this one as a duplicate depending on the test results.

Comment 7 John Villalovos 2008-08-15 13:28:40 EDT
Youquan,

Are there any BIOS settings which affect this?  I am trying to test on HEDT system with 0926 BIOS version
Comment 8 John Villalovos 2008-08-15 15:09:55 EDT
The BIOS on the system is SOX5810J.86A.1171.2008.0717.0926 so it is the 1171 BIOS.

Disregard BIOS revision I specified in Comment 7
