PEBKAC++. Multiple facepalm. I outdid myself here. I got lazy on the laptop install by copying config files from another machine... and it came back to bite me. Here was my /etc/fstab ... /dev/sda1 /boot vfat defaults,noatime 1 2 /dev/sda2 / ext3 noatime,nodiratime,async,user_xattr 0 1 /dev/sda3 none swap sw 0 0 ...but, but, but... this is a used Lenovo laptop, too old for UEFI, with only 75 gigs of disk and I've only got two partitions on it. I corrected fstab to the proper... /dev/sda1 / ext3 noatime,nodiratime,async,user_xattr 0 1 /dev/sda2 none swap sw 0 0 I'm surprised that LILO booted at all with the bad fstab. There were only some error message lines that scrolled by really fast at bootup. Otherwise a perfectly normal bootup. I finally got around to stopping the laptop in mid-bootup tonight, and looking at the error message. Something about fsck.ext3 not finding a magic superblock on /dev/sda2. This prompted me to dig through the system and find the problem. And, oh yeah, hibernate now works with one quirk. I assume hibernate was reading the swap partition name from /etc/fstab for hibernation. Of course it got "write error: No such device" when trying to save to a non-existant swap partition /dev/sda3. The one quirk is that bootup comes from the first menu item in LILO, unless I manually over-ride. I can parse the boot image name from /proc/cmdline and feed it into "lilo -R". Then I'll have to insert it into the hibernate shutdown scripts. -- I've seen things, you people wouldn't believe; Gopher, Netscape with frames, the first Browser Wars. Searching for pages with AltaVista, pop-up windows self-replicating, trying to uninstall RealPlayer. All those moments, will be lost in time like tears in rain... time to die.
