Most recent kernel where this bug did *NOT* occur: Distribution: Ubuntu Edgy Hardware Environment: Dell Inspiron 630m Software Environment: ? Problem Description: it is no problem for me, really, because I don't use MMC cards, but I thought it might help. I did send a report to the address in the log, but they directed me to report it here... this appears in the logs when suspending the machine.

Can you please check if the problem is still present in the 2.6.22-rc5 kernel?

Hi Rafael, my setup has changed a little since I reported the issue above. I now use Debian instead of Ubuntu, with kernel version 2.6.22-rc4, no grsec patch. During suspend&resume, the mmc and sdhci give no messages on the kernel log, but just work fine. If the bug was not related to grsec, then it could be fixed already. Thank you for your commitment!

OK, thanks for the information. I'm closing the bug, then.
