dmesg failure log at e255aee5b66ce4af025e6f77122114c01303b861
Hi,
Recent changes to the ACPICA subsystem(?) of the kernel, merged in
58a0228707870c8330917f919804986855443a19, causes at least one device (sample
set of one) to fail to boot.
A `git bisect` points towards one of those two commits (`git bisect
visualize`).

The latter (f8553720) does not build (skipped) and the former (e324e101)
building and bad. Their parent (f99b89ee) builds and is good.
Symptoms from that failure are that the sdhci subsystem(?) fails and mmcblk0
starts spewing errors -110. (mmcblk0: error -110 requesting status, mmc0: tried
to HW reset card, got error -110, mmcblk0: recovery failed!) causing I/O
errors. (Though, neither mmc nor sdhci parts of the kernel are at fault here.)
I have verified that everything seems right outside of the changes pointed out,
through lack of finesse and reverting the whole ACPICA merge.
See
https://github.com/samueldr/linux/commit/821a29d3a4278afbef16f561078e69d1b3d946fe
I am unable to find relevant log entries in `dmesg`, gathered using netconsole
for the failing boot. I have attached a good and failed boot. Good boot is from
the linked commit (revert) and the failing boot on the parent commit
(e255aee5b66ce4af025e6f77122114c01303b861).
Don't hesitate to ask if I forgot to include anything in the bug report. Also
don't hesitate to ask to test misc. scenarios to figure out better what's going
on.
