Description Geoff Gustafson 2008-04-01 14:58:09 EDT
It was just discovered that some buggy microcode fragments were mistakenly
included in the last version Red Hat pulled into 4.7. Intel is posting a new
version to downloadcenter.intel.com (search for "processor microcode", pick some
recent processor, select Linux). The version should be 20080401.

Version-Release number of selected component (if applicable):

Created attachment 299963 [details]
updated microcode from 4/1/08

The intel.com website seems slow to update, so here is the file.
Comment 2 Geoff Gustafson 2008-04-01 16:17:12 EDT
Sorry, apparently I put this under 5.3 accidentally but it needs to be
considered for 5.2.
Comment 3 Geoff Gustafson 2008-04-02 11:16:45 EDT
The buggy version can cause a hang when the microcode is loaded on Xeon boxes
with family 15, model 2, stepping 2, and family 15, model 1, stepping 1.

This will be carried forward in the original BZ 431566.
