it's a cdrecord option, I've never used k3b so cannot comment on how to
make it enable that.

Hmm, I'll take a look, but I don't really think it is a problem of the recording programme, otherwise how could my reader read it out completely?


It isn't a problem of the recorder program. But some drives wont read
the very end of a disc unless there are some pad blocks at the end.
Thus, you should always use the cdrecord pad option.

Well, I now used the -pad option, but now the image (naturally) gets larger and thus k3b reports verify fail. I think the k3b people need to ignore the last 00s and calc the md5sum according to the original iso size...

Don't remember, sorry :)

I probably will make a new topic regarding issues (I think) I found with the new mm kernel.


Fine, check the SG_IO thing first though.

I am sorry, but could you explain how to find out? I dunno where to look... But I made your vmstat output:
