This update breaks booting on my Lenovo T540p. It hangs at startup trying to run
a start job on an LVM PV (which is part of a LUKS-encrypted partition).
This update contains the TSX disable change that Intel released for Haswell CPUs
because TSX is broken. glibc in F21 defaults to using TSX for lock elision and
it will explode if the microcode update is applied after it's running. The main
solution is early microcode loading. Fedora isn't setup yet to do early
microcode updates for F21 because we need to change things in the kernel and in
the creation of the initramfs by default. See bug 1083716
This update prevents my / and /home and other from getting decrypted, thus
making the system unusable. Also, it will of course be pulled in with today's
netinst f21 reinstall.
On my ThinkPad x240 I too was affected by all the programs crashing with SIGILL
trying to execute the XBEGIN instruction. After installing the latest firmware
update from Lenovo, the CPU no longer advertises the "rtm" feature and
everything works for me again.
