I’ve tested 3.2.0-13.22 and the results are… annoyingly varied

Okay, I’ve tested 3.2.0-13.22 and the results are… annoyingly varied. Mostly the boots ended in a black, nonresponsive screen. On a couple of such boots, I was able to ssh in and get some logs. I’ll attach them.

On one boot, there was a Trace different from the panic I reported. I’ll attach a picture.

On yet another boot, the same panic was there just as in my shots above, just after ”Starting CUPS” this time. I’ll attach a picture of that too just for completeness’ sake.

So the issue is definitely still there, either it just now manifests itself in slightly more random ways or is clouded by others. I tried -12 again too and that immediately produced the panic, so it’s more consistent in that respect.

On a positive note, fbdev still Just Works.

This really is a messy one

@Bryce, this really is a messy one: I’ve so far dissected three overlapping issues ((Bug #926007Bug #926012 and Bug #926028) which have hindered my attempts to assist in debugging the one I originally laid down in this report. :)

Resume normal boot fails to launch X when using fbdev

3. helmikuuta 2012 klo 14.44
Sijainti: Vianhallintajärjestelmät: Launchpad
Avainsanat: Ubuntu

Due to Bug #926007, I’m forced to use fbdev on this laptop in order to use X. In normal use it works okay, but when I boot in recovery mode, the resume normal boot option fails to launch X. Instead it launches the low graphics mode dialog, and if I switch to VT-1, the screen becomes garbled.

Xorg log says the problem is it can’t open /dev/fb0: No such file or directory. I’ll attach the log below.

It doesn’t matter whether or not I use the other options the recovery ncurses menu offers; X won’t start properly unless I reset and boot normally (i.e. not in recovery mode).

Freezes during boot when wistron_btns loaded

With the recent Precise kernels (at least 3.2.0-[10-12] I think), the system freezes during boot with the Ubuntu logo and colored dots on screen (the dots stop progressing), when I have wistron_btns enabled in /etc/modules. I need wistron_btns on this laptop for the wireless to work, which is why I’d like to have it enabled.

This is unrelated to Bug #926007 which I also just filed: the wistron_btns freeze happens even when I’m using fbdev. (With -intel, the #926007 panic and this freeze take turns in who gets to mess with me.)

From what I’ve gathered so far, it seems that wistron_btns works fine if I manually modprobe it from my desktop, after booting without it. So that’s a workaround at least.

I can kill the freeze with Alt+PrtSc+REISUB. I’ll provide any additional info needed, though I don’t know how to produce logs when the system is frozen.

Panic, Attempted to kill init. ? printk+0x2d/0x2f

(Filing this a a separate issue as suggested by Bryce Harrington in comments of Bug #903831.)

With the -intel driver specified in xorg.conf (or without an xorg.conf so that -intel is used), booting Precise with the current 3.2.0-12 always results in a kernel panic. I’ll attach a couple of shots I took of two instances (although to me the panic looks the same in both cases).

This began within the Precise cycle: with the early kernels I was able to boot fine, although Bug #903831 did come up then.

I have yet to try 3.2.0-13 which has just been released. Once package listings pick it up I’ll give it a go and report back.

I’m able to boot by switching to fbdev in xorg.conf (the way I’m reporting this now).

Bug #904853 is related

Bug #904853 is related: for a i386 package installed with –force-architecture on an amd64 system, the Synaptic symptom is the same (”The list of installed files is only available for installed packages” ). The info files in /var/lib/dpkg/info don’t have a :i386 in the filename, as (I’m guessing) Synaptic figures for an :i386 package they should.

jani@saegusa:tmp$ ls /var/lib/dpkg/info/lightscribe*
/var/lib/dpkg/info/lightscribe.conffiles /var/lib/dpkg/info/lightscribe.list /var/lib/dpkg/info/lightscribe.postinst

This has been fixed in Precise (if not earlier)

This has been fixed in Precise (if not earlier): libsane depends on libsane-common, which now provides html/sane-mfgs.html.

jani@saegusa:~$ dlocate sane-mfgs.html
libsane-common: /usr/share/doc/libsane/html/sane-mfgs.html
jani@saegusa:~$ LC_ALL=C apt-cache depends libsane | grep libsane

This also concerns libsane 1.0.22-7ubuntu1 here

This also concerns libsane 1.0.22-7ubuntu1 here. I don’t think this is Bug #904853, as I’ve not installed these packages manually, although I can’t vouch if –force-acrchitecture is used automatically by some upgrades.

The two dialogs are very, very inconsistent

2. helmikuuta 2012 klo 14.30
Sijainti: Vianhallintajärjestelmät: Launchpad
Avainsanat: Apport, saavutettavuus, Ubuntu

The two dialogs are very, very inconsistent: the dialog icon they use (DIALOG_QUESTION in one, the DIALOG_ERROR in the other), the dialog window title (”Application problem” vs. none), the dialog title and explanation style (brief vs. verbose), the ignore option missing from one… It’s almost as if the engineers behind the two dialogs have intentionally tried to make them as different from one another as possible. (No offence intended, I just think it’s funny although it is a genuine accessibility problem as well.) Also, one dialog seems to be minimizable whereas the other is not — though this doesn’t appear in Blair’s screenshot; it may be something introduced in Precise which the system my screenshot is from is running.
