/usr/bin/cdrecord: Resource temporarily unavailable. Cannot get mmap for 4198400 Byte

i have this error message when i try to erase cd-rw or burn audio trackswith k3b (or other burning applications) as user. I't's all ok if i try do to the same thing like root.
I already used k3bset to change permission on cdrecord.
Any idea?
thanks.

I have the same problem too, the only way to get around it is to burn as root. I believe an update to the kernel doesn't allow a user to burn unless they are the root.

Nope, just updated to 2.6.17-1.2139_FC5 and still same error

Yes, it's been like this for the past few kernel versions. Originally when burning did work under k3b as a user it was because it would change some permissions and stuff. I think because of security reasons, the newer kernels don't allow it.

As far as I can remember we had this once on FC3 or FC4 too. It was fixed in the comming kernel version, but now it takes more time
OK, I still have to burn as root.

I have never had a problem burning with k3b as user. I have not tried with the latest 2.6.17 (just updated yesterday), but with all other kernels I have burned as user.

This topic has been covered, but I don't recall if there was a solution or what that solution might have been. Try the search. There should be something there.

Yea I really hope they make it the way it was. That's the worst bug when something works fine then because of a change, some cool feature doesn't work.

It's even listed in bugzilla for more than 2 months:

cdrecord mustn't be run suid root, and the device permissions on the burner must be set to 666 (use udev for this).
