Description Tom Horsley 2012-06-11 10:01:59 EDT
Description of problem: I added boot_delay=100 to my kernel args to try and capture a kernel walkback message. When rebooting the system I typed 'e' in the grub2 menu to edit the kernel command line to remove this so rebooting would work faster. I moved the cursor (painfully slowly) out to the start of the boot_delay I had put on the end of a very long line. I typed "del" about 3 or 4 times to delete the characters at the end, and after those 3 or 4 times, my system apparently froze up. I couldn't delete any more characters, I couldn't hit ESC to get back to grub menu, nothing worked. Even Ctrl-Alt-Del didn't work. I had to power cycle the machine to get back. It is a very long line. I don't know if the line wrapping messed it up. Version-Release number of selected component (if applicable): grub2-2.0-0.25.beta4.fc17.x86_64 How reproducible: Only tried it once so far. Steps to Reproduce: 1. see above 2. 3. Actual results: frozen system Expected results: ability to edit kernel command line. Additional info:

This should be fixed in http://koji.fedoraproject.org/koji/buildinfo?buildID=322368 - please confirm.

Created attachment 590944 [details] The grub.cfg file I tried to edit the 1st kernel entry in Here's the grub.cfg file I was trying to edit. The line is very long. It wrapped even on the 1920x1200 monitor I have.
Comment 3 Tom Horsley 2012-06-11 11:47:16 EDT
OK, I got the beta6 installed (after discovering that the rpm apparently doesn't do the grub2-install for me :-), and I didn't freeze my system, but the editing still didn't work: In this case I moved the cursor down to the line ending in boot_delay=100. I then type Ctrl-E to get to the end. I then hit the backspace key 14 times to erase the boot_delay=100 string, but the screen still said "boot_del", so it stopped erasing characters on the display about half way through. I then when ahead and rebooted with that edited kernel entry, and the /var/log/messages "kernel command line" message does not have a boot_del on the end, so it apparently erased the whole thing as far as booting is concerned, but it still has a real problem with the way it displays the edits on the screen.
Comment 4 Mads Kiilerich 2012-06-11 12:04:57 EDT
Did you have a line wrap after "boot_del" ... or can you attach a photo to explain exactly how it looked like? Was it possible to move the cursor around and edit elsewhere after the erasing had stopped working?
Comment 5 Tom Horsley 2012-06-11 12:17:24 EDT
The line wrap was right after the q in the "quiet" parameter just before the boot_delay=100. The cursor continued to move even after it stopped erasing characters from the screen, so what I saw was something like: long line... q\ uiet^boot_del Where the ^ indicates the cursor position. I didn't try doing a lot of other editing this time, I suspect the fact that I did try doing a lot of cursor movement and trying different things the first time is what got my system frozen :-).
Comment 6 Mads Kiilerich 2012-06-11 18:18:34 EDT
I'm sorry - that build did not contain the patches I thought it did. Please try again with this snapshot in an unofficial scratch build: http://koji.fedoraproject.org/koji/taskinfo?taskID=4152623 grub2-2.0-0.37.beta6.4462.fc17
Comment 7 Tom Horsley 2012-06-12 08:03:55 EDT
Yep. The grub2-2.0-0.37.beta6.4462.fc17 does indeed seem to fix the editing problems. I could delete characters through the line wrap, then type more characters to make the line wrap again, and everything worked correctly.
Comment 8 Fedora End Of Life 2013-07-03 22:38:02 EDT
This message is a reminder that Fedora 17 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 17. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '17'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 17's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 17 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior to Fedora 17's end of life. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Comment 9 Fedora End Of Life 2013-08-01 04:55:42 EDT
Fedora 17 changed to end-of-life (EOL) status on 2013-07-30. Fedora 17 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
