[SOLVED] Problem with hosts getting stuck at GRUB menu list
I have an interesting problem. I administer about 300+ Debian and SuSE hosts. These hosts are all connected to networked Raritan devices for KVM, and also have serial console connections
Occasionally, when the host is rebooted, we find that the host gets stuck at the GRUB menu when it boots up, as if a key is being pressed. We're not able to figure out which key seems to be "leaked" by the KVM or the serial console, So now I'm trying to figure out a solution so that the hosts do not get stuck. I think one solution would be to remove the timeout, but I'd prefer to keep that there if possible.
I'm wondering, is there a way to:
A. Ignore keypresses except for certain ones (e.g. Arrow Down, etc). Narrowing down the options would certainly reduce the window of this interruption
B. Have GRUB boot the selected line without waiting for the Enter key to be pressed. When the hosts are stuck at this menu, they are always sitting on the first (default) line
I've browsed the GRUB information pages, but haven't come across anything yet.
Thanks in advance for your help/suggestions
