Future wise, rather than solely sending links to bugreports, please
copy the relevant data into the email. Moreover, we don't normally
care that much about "old" kernels, unless problems exists on the
latest kernels as well.
Anyway, by following the above links, I figured this is about
sdhci-pci and you get a CRC problem when switching to HS400 mode.
[ 3.673358] mmc0: error -84 whilst initialising MMC card
[ 3.808029] mmc0: mmc_select_hs400 failed, error -84
A wild shot is to try out my fixes branch, which holds the following
below queued fix, that might solve the problem if it's a regression.
