Subject: [sdhci] laptop hangs at random after suspend  / resume

Hi,

this module has the tendency of hanging my laptop after suspend /resume. 
(random issue).

blacklisting the module makes the problem go away.

I never bothered to report this since it was an isolated issue on a 
laptop where this module was problematic in the past.. [bug 9905 from 
bugzilla]

but now ive found someone with different hardware that is likely to have 
this issue too: https://bbs.archlinux.org/viewtopic.php?pid=1010070

i would like to help debug this issue. but i would not know where to 
start. the hangs happen after several hours of usage / multimple 
suspend-resume cycles. usually takes over 12hs to happen.

attaching a dmesg + lspci -vvnn in casie it helps...

please CC me in replies since im not subscribed to the list.
