Package: intel-microcode
Version: 3.20160607.1
Severity: important
Erratum BDF90 (BDX90?) for the Xeon E7v4 (and maybe Xeon E5v4) may
result in a hung system on all affected processors when a microcode
update is attempted during boot on a Debian system with the
intel-microcode package installed.
If this errata is being triggered on a system and causing boot hangs,
please boot the kernel using the "dis_ucode_ldr" parameter to bypass the
kernel microcode loader, as described in the intel-microcode package
documentation (README.Debian):
https://sources.debian.net/src/intel-microcode/3.20161104.1/debian/README.Debian/#L104
Known details about BDF90:
Intel® Xeon® Processor E7-8800/4800 v4 Product Family Specification
Update, April 2017:
BDF90 - Loading Microcode Updates or Executing an Authenticated Code
Module May Result in a System Hang
Problem: An uncorrectable error (IA32_MC3_STATUS.MCACOD=0400 and
IA32_MC3_STATUS.MSCOD=0080) may be logged for processors that have
more than 2.5MB last-level-cache per core on attempting to load a
microcode update or execute an authenticated code module. This issue
does not occur with microcode updates with a signature of 0x0b000021
and greater.
Implication: Due to this erratum, the processor may hang when
attempting to load a microcode update or execute an authenticated
code module.
Known-affected processors (list may be incomplete):
Xeon E7-8891v4
Xeon E7-8893v4
Other possibily-affected processors (incomplete list):
Xeon E5-2667v4
Xeon E5-2643v4
Xeon E5-2637v4
Xeon E5-4655v4
This erratum is worked around by microcode revision 0xb000021, included
in the intel-microcode 20170511 release (which will be uploaded soon).

sig 0x000506e3, pf_mask 0x36, 2017-04-09, rev 0x00ba, size 98304
+ This release fixes undisclosed errata on the desktop, mobile and
server processor models from the Haswell, Broadwell, and Skylake
families, including even the high-end multi-socket server Xeons
+ Likely fix the TSC-Deadline LAPIC errata (BDF89, SKL142 and
similar) on several processor families
+ Fix erratum BDF90 on Xeon E7v4, E5v4(?) (closes: #862606)
+ Likely fix serious or critical Skylake errata: SKL138/144,
SKL137/145, SLK149
* Likely fix nightmare-level Skylake erratum SKL150. Fortunately,
either this erratum is very-low-hitting, or gcc/clang/icc/msvc
won't usually issue the affected opcode pattern and it ends up
being rare.
SKL150 - Short loops using both the AH/BH/CH/DH registers and
the corresponding wide register *may* result in unpredictable
system behavior. Requires both logical processors of the same
core (i.e. sibling hyperthreads) to be active to trigger, as
well as a "complex set of micro-architectural conditions"
* source: remove unneeded intel-ucode/ directory
Since release 20170511, upstream ships the microcodes both in .dat
format, and as Linux-style split /lib/firmware/intel-ucode files.
It is simpler to just use the .dat format file for now, so remove
the intel-ucode/ directory. Note: before removal, it was verified
that there were no discrepancies between the two microcode sets
(.dat and intel-ucode/)
* source: remove superseded upstream data file: 20161104
