<HTML><BODY>I have swap in sda1 and "/" in sda2 partitions of HDD. At installation of OpenSUSE 12.3 (where YaST2 is used) on my cluster node I found erroneous, by my opinion, boot loader (GRUB2) settings.<br><br>YaST2 proposed (at installation) to use <br>... resume=/dev/disk/by-id/ata-WDC-... -part1 splash=silent ...<br><br>in configuration of GRUB2. This parameters are transmitted (at linux loading) by GRUB2 to linux kernel. GRUB2 itself, according my installation settings, was installed to MBR. I changed (at installation stage) -part1 to -part2, but after that YaST2 restored it back to - part1 value ! <br>And after installation OpenSuSE boots successfully ! <br>I found (in installed OpenSuSE) 2 GRUB2 configuration files w/erroneous -part1 setting.<br><br>I found possible interpretation of this behaviour in /var/log/messages. I found in this file the strings:<br>[Kernel] PM: Checking hibernation image partition /dev/disk/by-id/ata-WDC_...-part1<br><br>[Kernel] PM: Hibernation Image partition 8:1 present<br>[Kernel] PM: Looking for hibernation image.<br>{Kernel] PM: Image not found (code -22)<br>[Kernel] PM: Hibernation Image partitions not present or could not be loaded<br><br>What does it means ? The hibernation image is writing to swap partition ? But I beleive that hibernation is really suppressed in my Linux (cpufreq kernel modules are not loaded) , and my BIOS settings do not allow any changes of CPU frequency. BTW, my swap partition is small (4 GB, but RAM size is 8 GB).<br><br>Which GRUB2/resume settings are really right and why they are right ?<br><br>Mikhail Kuzminsky<br>Computer Assistance to Chemical Research Center RAS<br>Zelinsky Institute of Organic Chemistry<br>Moscow<br><br><br><br><br><br><br></BODY></HTML>
