+ Removed Microcodes:
sig 0x000106e4, pf mask 0x09, 2010-03-08, rev 0x0002, size 5120
+ This microcode update has been documented by Intel to fix a severe
security issue (refer to LP bug 1212497); This update is known to fix
several nasty errata on 1st to 4th gens of Core i3/i5/i7, and Xeon
5500 and later, including but not limited to:
+ AAK167/BT248: Virtual APIC accesses with 32-bit PAE paging
may cause system crash
+ AAK170/BT246: The upper 32 bits of CR3 may be incorrectly used
with 32-bit paging
+ Erratum AAK167/BT248 is nasty: "If a logical processor has EPT (Extended
Page Tables) enabled, is using 32-bit PAE paging, and accesses the
virtual-APIC page then a complex sequence of internal processor
micro-architectural events may cause an incorrect address translation or
machine check on either logical processor. This erratum may result in
unexpected faults, an uncorrectable TLB error logged in
IA32_MCi_STATUS.MCACOD (bits [15:0]), a guest or hypervisor crash, or
other unpredictable system behavior"
* kernel preinst: simplify and load microcode and cpuid modules
* postinst: attempt to load microcode module (closes: #692535)
* Remove from the source package an unused upstream microcode bundle,
which has been completely superseded by later bundles:
microcode-20130222.dat
* Use 1.20130808.0+deb7u1 as the Debian version to start a new branch that
sorts before 1.20130808.1, which was uploaded to unstable. Further
updates targeting stable will go into the 1.x branch. Further updates
targeting unstable and stable-backports will go into the 2.x branch
