Could you please apply the patch to your HAL and reproduce the coldplug and attach the trace?

is /sys/class/mmc_host/mmc0/mmc0:ffff/device present if the card is inserted? What is the target of the link?

Comment 7 Frederic Crozat 2008-03-14 12:58:02 UTC

no, there is no device symlink in /sts/class/mmc_host/mmc0/mmc0:ffff/

I assume that's the problem. AFAIK a kernel bug. Maybe try latest kernel and/or latest hal version (git). 

Feel free to reopen if the problem is still there with the latest versions (or connect me via SUSE ;-) ).
