Hallo, I've tested 2.4.0prerelease pure - ac1-ac2-ac3-ac4-ac5 and my system crashed whenever I left X. Having switched back to 2.4.0-test13pre7 all is fine. I'm no developer, so if you need more information, give me some hints. kind regards Norbert - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
