[Bug 577720] New: kiwi: Kernel messages should not be overlaid on the boot splash
http://bugzilla.novell.com/show_bug.cgi?id=577720 http://bugzilla.novell.com/show_bug.cgi?id=577720#c0 Summary: kiwi: Kernel messages should not be overlaid on the boot splash Classification: openSUSE Product: openSUSE.org Version: unspecified Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: System Imaging AssignedTo: ms@novell.com ReportedBy: federico@novell.com QAContact: adrian@novell.com Found By: Development Blocker: --- Created an attachment (id=341141) --> (http://bugzilla.novell.com/attachment.cgi?id=341141) kiwi-bnc574605-no-boot-messages.patch This bug appeared initially as bug #574065. The grub configuration files that kiwi generates don't supress kernel messages with the "quiet" option, so there is visible kernel spew during the first boots. This looks bad over the graphical boot splash. See attachment #339285 for a picture. The attached patch adds "quiet" for all cases except the failsafe ones, where you probably do want to see any messages. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The splash screen stays visible without being destroyed by any kernel message in all my tests. Frankly said I don't want to skip these messages they can help if something goes wrong and would also be different from our standard installation workflow with yast. We don't add "quiet" there too Steffen can you have a look at this ? -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Why would you want to add a 'quiet' to all boot entries? That's what splash=silent already is for. Judging from the screenshot this is rather a kernel bug not taking care of the splash screen properly. A wild guess: kms/drm related? Didn't Takashi write something about fixing bootsplash with kms some time ago on the SuSE kernel list? Looks more like something for the Moblin guys than kiwi. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

From a quick reading of bootsplash.c, using "splash=silent" doesn't really mean
http://bugzilla.novell.com/show_bug.cgi?id=577720 http://bugzilla.novell.com/show_bug.cgi?id=577720#c4 --- Comment #4 from Federico Mena Quintero <federico@novell.com> 2010-02-08 21:10:10 UTC --- All I know is that with "quiet" we don't get messages, and without it we do :) that you won't get kernel messages on the console; it just affects how the splash gets rendered. "quiet" means "don't show kernel messages below log level 4" (see linux/init/main.c:quiet_kernel()). Warnings and messages for when "something goes wrong" *will* be shown, as far as I can tell, which should be enough to diagnose problems. Even with "splash=silent quiet" enabled, there are still some messages overlaid on the splash, but these seem to come from Kiwi itself. Maybe Kiwi is writing directly to /dev/console or something like that? Marcus, if you can't reproduce this, try one of the Moblin 2.1 images from http://moblin-build.boston.ximian.com/ -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Using 'quiet" to hush up the issue is the wrong way, IMO. You might as well tell the user to hide her eyes for some seconds so she doesn't see the messages. Federico, I don't see why you defend an obviously broken kernel. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
