I edited sysctl.conf and rebooted. Using the key sequence, I can reboot my machine when things are good. But, just a few minutes ago, it locked up completely. I was looking at a frozen screen and trying the alt-sysrq REISUB did nothing. I had to hit the power switch. Also, I'm unable to ssh into the box when its locked up. Nothing seems to hit /var/log/messages right before the lockups. Is there any other location I can look at for post-mortem clues? - -- Steve -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkmlS8UACgkQeERILVgMyvAY1wCeMB06c0G3uvvOF+W6rspPBRrg uAMAn0EZPCseAV4F1x9wM0Nf8Ar+h/mb =OSh2 -----END PGP SIGNATURE----- -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
