Description Juergen Weigert 2008-10-29 14:01:28 UTC

This is a lonovo x60s running opensuse 11.0

I have an SDcard inserted in the builtin card reader.
both suspend and resume appear to hang. It helps to hit several keys and to insert remove the SDcard while suspending/resuming.

After several attempts verifying that this is indeed related to the SDcard, dmesg has this:
mmc0: Timeout waiting for hardware interrupt.

Jürgen, please feel free to also test 11.1. Beta. It would be very interesting if the problem occurs there as well.

Comment 2 Juergen Weigert 2008-10-29 17:58:10 UTC

Testing 11.1 beta3 with kde4

Using the tiny triangle in the power down menu, I found a suspend-to-ram function. Appears to work fine, with or without inserted SDcard.

Comment 3 Frank Seidel 2008-11-03 10:40:09 UTC

ok, then this bug is not present any more, correct?
