Description Felix Triebel 2007-01-25 12:41:18 UTC 
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.

Steps to reproduce:
every time on suspend/resume
Comment 1 Rafael J. Wysocki 2007-06-18 10:08:28 UTC 
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.
