However, this microcode should be 0x2d, that's what is included in the intel-microcode 20150107. Because it looks like the microcode was not updated, which would point to a kernel bug and not a intel-microcode bug. I need to know if this cpuinfo comes with or without the intel-microcode package installed. And if it is installed, I need the contents of /var/log/dmesg, please. That said, Intel just published release 20150121, which is also a fast-track emergency update... and it DOWNGRADES that microcode to release 0x29, which is what was in release 20140913 (the previous Debian release) AND it is earlier than what you system has in the BIOS. So here's what you have to do: 1. Remove the intel-microcode package from your system, update the initramfs and reboot (update-initramfs -u). 2. Ensure that the microcode was not updated by Linux (check the kernel log, or post the contents of /var/log/dmesg after the reboot to this bug report). 3. If your microcode is still version 0x2a, contact Dell support for a beta BIOS update with fixed microcode. > Let us know if you need anything else. I'd like to know why that microcode was version 0x2a, please. And also, if removing intel-microcode (or downgrading it to version 20140913) fixes your problem...
