Subject: live-boot: consider reporting IO errors to X users (now they see only green background and mouse cursor)
Date: Tue, 08 Feb 2011 23:15:01 +0200
[Message part 1 (text/plain, inline)]
Package: live-boot
Version: 2.0.15-1
Severity: wishlist

Steps to reproduce:
1) script -c 'set -x; ls -a; sudo lb config --packages "gnome wireless-tools wpasupplicant" -d squeeze -b usb-hdd -p standard-x11 -m http://apt-proxy:9999/debian --bootappend-live "live-config.keyboard-layouts=fi" --linux-flavours 486 --binary-indices false --apt apt --memtest memtest86+ --debian-installer live --debian-installer-gui true --win32-loader false && sudo lb build'
2) write the resulting binary.img to an USB drive
3) boot the USB drive

Expected results:
3) the live system either boots or informs the user about an error

Actual results:
3) At a low probability the boot fails. User sees just a green
background and a mouse cursor that can be moved. Screenshot is
attached as gnome_green_background1.jpg

More info:
1) This happens quite rarely, rebooting the computer was enough to
make it boot successfully. The cause of the failure is not important
here. This wishlist bug is about improving error reporting so that
people can detect and report such failures in the first place.
2) When I told the user that he should try ctrl-alt-f1 he was able to
see squashfs read errors. Attached as squash_error_unable_to_read_page1.png
3) md5sum -c md5sums.txt says "OK" for all files
4) Would it be possible to switch out of X if read errors are
detected? Would KMS make it possible for kernel to print the errors on
top of X?

Thinking about this again, I'm afraid this is not fixable at all in a
generic way and the only thing you can rely on is to educate people to
look at the logs (as in 'switch to tty1 and read the messages shown there).
