Try adding "reboot=h" on the end of your kernel parameters in /boot/grub/grub.conf. For example: kernel /boot/vmlinuz-2.6.18-8.1.14.el5 ro root=LABEL=/1 rhgb quiet reboot=h -- Andrew Tried this no change to behaviour Anything else I should try or information I can provide ? :) Clint Clint, I had this same problem with the Dell Optiplex 745, but I'm running RHEL5. I assume you also rebooted after making the change to grub to make it active? The "reboot" kernel argument can take several options. I tried them each until I found one that worked. Here's the info regarding the reboot argument: This option controls the type of reboot that Linux will do when it resets the computer (typically via /sbin/init handling a Control-Alt-Delete). The default as of v2.0 kernels is to do a `cold' reboot (i.e. full reset, BIOS does memory check, etc.) instead of a `warm' reboot (i.e. no full reset, no memory check). It was changed to be cold by default since that tends to work on cheap/broken hardware that fails to reboot when a warm reboot is requested. To get the old behaviour (i.e. warm reboots) use reboot=w or in fact any word that starts with w will work. Other accepted options are `c', `b', `h', and `s', for cold, bios, hard, and SMP respectively. The `s' takes an optional digit to specify which CPU should handle the reboot. Options can be combined where it makes sense, i.e. reboot=b,s2 -- From http://tldp.org/HOWTO/BootPrompt-HOWTO-3.html Hi It turns out the reboot=b option works for me. Thanks for the help. I guess this is more of a feature than a bug :) |
