Removing the two lines as suggested by Steve Langasek above caused the machine to boot. (However nothing was displayed on the serial console until it finished booting.)
A number of other machines in this environment are booting with these lines in their menu.lst -- at a first look it appears to be only the HP ML110s that are not booting when they are present, but I will add any additional hardware that exhibits this behavior to this bug. -- HP ML110 fails to boot with grub after server install via PXE / serial console https://bugs.launchpad.net/bugs/356518 You received this bug notification because you are a member of Ubuntu Foundations Team, which is a bug assignee. Status in “grub” source package in Ubuntu: New Bug description: I am seeing the following behavior on two HP ML110s: The install of the Jaunty image is performed via PXE through the serial console. The install proceeds normally and the machine reboots at the end. However, the machine does not properly boot from the internal hard disk via GRUB, instead hanging at "GRUB loading, please wait..." This occurs whether using the amd64 or i386 image. Replacing GRUB with LILO causes the machine to boot properly, so the install seems to be okay... it is only the boot loader that seems to have an issue. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-foundations Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-foundations More help : https://help.launchpad.net/ListHelp
