Comment 82 for bug 1216583

I did the following:

in file /etc/modules:

# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

lp
rtc
pciehp

Then I tried this:

pciehp.pciehp_force=1

pciehp.pciehp_poll=1

elevator=noop

...and the combinations:

pciehp.pciehp_force=1 pciehp.pciehp_poll=1

pciehp.pciehp_force=1 elevator=noop

pciehp.pciehp_poll=1 elevator=noop

pciehp.pciehp_force=1 pciehp.pciehp_poll=1 elevator=noop

The last was:
muede@muede-nb:~$ cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-3.13.0-031300rc6-generic root=UUID=85259d26-9563-45e4-a36f-8f6c19ac62aa ro quiet splash vt.handoff=7 pciehp.pciehp_force=1 pciehp.pciehp_poll=1 elevator=noop

...and always came:

[ 112.464105] sdhci: Timeout waiting for Buffer Read Ready interrupt during tuning procedure, falling back to fixed sampling clock

So I would say, that nothing has changed.
