Bug#412915: linux-image-2.6.18-4-686: mmc/sdhci problems after resume from ram
Package: linux-image-2.6.18-4-686
Version: 2.6.18.dfsg.1-11
Severity: normal
Hi,
after resuming from suspend-to-ram (suspended with s2ram from
uswsusp/unstable) mmc_core and sdhci spit out tons of errors and make the
system very unresponsive. Eventually the system freezes (or
unresponsiveness >>> my patience), a quick shutdown after resume usually helps.
a few lines from syslog:

The mmc messages are repeated in differing amounts of the single messages
again and again, each message is followed (or preceded?) by the following sdhci messages:

Suspend-to-Ram (and resume) with the two modules mmc_core and sdhci unloaded
just works fine. Since I don't need the card reader (not sure if it even
works) I'll probably just blacklist these modules ...
