I didn't use USB at the time, it was really running a Maemo Mapper
download via WLAN which caused the problem. Sometimes the app also got
stuck and there were kernel messages about the MMC card; seems like I
need to investigate a bit more to provide a proper report.

In the meantime I also saw the "memory corruption during WLAN" bug
(https://bugs.maemo.org/show_bug.cgi?id=2006). I'll check whether that
happens for me.

I know, I just wondered whether filing a bug for the 770 kernel anywhere
else would get the necessary attention. I take your statement as an
encouragement to file a bug report in the normal bugs.maemo.org...
