****** kernel: CPU0 microcode updated early to revision 0x70a, date = 2010-09-29 which is quite different from the latest intel-microcode upgrade: ******* intel-microcode (3.20150121.1) unstable; urgency=critical * New upstream microcode data file 20150121 * Downgraded microcodes (to a previously shipped revision): sig 0x000306f2, pf mask 0x6f, 2014-09-03, rev 0x0029, size 28672 * The microcode downgrade fixes a very nasty regression on Xeon E5v3 processors (closes: #776431) * critical urgency: the broken sig 0x306f2, rev 0x2b microcode shipped in release 20150107 caused CPU core hangs and Linux boot failures. The upstream fix was to downgrade it to the same microcode revision that was shipped in release 20140913 * source: remove superseded upstream data file: 20150107. * initramfs.hook: do not mix arrays and lists. Avoid echo "foo $@", use echo "foo $*" instead. This is unlikely to be expĺoitable, but it makes ShellCheck happier. -- Henrique de Moraes Holschuh <[email protected]> Wed, 28 Jan 2015 20:03:20 -0200 ******* both 'date' and 'rev' are not the same, which let me think that the 'builtin microcode'is loaded instead of the intel-microcode file. So i also wonder if iucode-tool is able to deal with systemd, as its latest upgrade is quite older than the ubuntu's systemd use. intel cpu q9550 : http://ark.intel.com/products/33924/Intel-Core2-Quad- Processor-Q9550-12M-Cache-2_83-GHz-1333-MHz-FSB oem@u32:~$ ubuntu-drivers devices == cpu-microcode.py == driver : intel-microcode - distro non-free ....
