This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- trusty' to 'verification-done-trusty'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

[Bug 1310800] Re: 056a:0302 Trusty Tahr, kernel 3.13: automatic load of wacom.ko driver cause a hard kernel panic
I've taken a long hard look at this bug and believe I've been able to nail down the cause. The panic is caused by a NULL pointer being passed to the 'input_report_switch' function. It occurs if the kernel has probed the tablet's pen/pad interface and processes a status report from it before the kernel has a chance to probe the tablet's touchpad interface. The suggested workaround of loading the module before connecting the tablet only masks the issue by changing the timing of events enough so that the kernel is able to finish probing both interfaces before processing the status report. This issue was addressed upstream by commit 44b9683 (HID: wacom - make sure touch_input is valid before using it) which is part of the 3.19 kernel. Both the Trusty (3.13) and Vivid (3.16) kernels are missing this patch, however. Commit 44b9683 can be trivially backported; I've attached such a backport for convenience. ** Patch added: Upstream 44b9683 modified to apply against Ubuntu's 3.13 and 3.16 kernels https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1310800/+attachment/4452940/+files/make-sure-touch_input-is-valid-before-using.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1310800 Title: 056a:0302 Trusty Tahr, kernel 3.13: automatic load of wacom.ko driver cause a hard kernel panic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1310800/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I have a new incarnation of the bug, but I am not being able to capture a track, although is quite easy to trigger. Steps: 1 - load wacom.ko 2- connect the tablet **wirelessly** 3- wait until the tablet go to deep sleep (around 10 minutes) 4- switch the tablet on - hard crash, the PC is completely dead.

I can reliably trigger this bug on my machine in the 3.16 and 3.13 kernels. I've attached the kernel crash output for 3.16 (minus the dump because of its size, I can provide a link if desired).

[Bug 1310800] Re: 056a:0302 Trusty Tahr, kernel 3.13: automatic load of wacom.ko driver cause a hard kernel panic
So I have a system that this happens to. Tablet model is CTH480S. The thing is that this setup used to work until today (kernel update 2 days ago? Although running with an old version of the kernel show the same problem now). The work around is add wacom into /etc/modules for now, if anyone is interested. This adds wacom to be loaded at boot time.

I have attached dump files. I note: BUG: unable to handle kernel NULL pointer dereference at 0018 - may be a clue? I have also posted upstream as suggested but that thread seems to have found a work-around so may be less interested. This seems to be an issue with how Ubuntu packages this module and should be fixed out-of-the-box rather than requiring (geeky) workarounds.

I can confirm exact same results with wacom Intuos. Booting with tablet plugged in does not crash. Plugging tablet in after booting triggers kernel panic.

I guess it's down to me then... Changed back to 'Confirmed', since the problem is readily reproducible for me, although it doesn't occur every time -- once I plugged the tablet in without triggering a crash (and it then worked correctly in my limited testing). I've tried persuading this USB-stick-based system to save kernel crash dumps, without success so far.

[Bug 1310800] Re: 056a:0302 Trusty Tahr, kernel 3.13: automatic load of wacom.ko driver cause a hard kernel panic
For completeness, here's my panic, transcribed manually from my netbook (there may be typos). (Not sure how useful this will be since it's not the whole backtrace.) ...

[Bug 1310800] Re: 056a:0302 Trusty Tahr, kernel 3.13: automatic load of wacom.ko driver cause a hard kernel panic
I was not really able to reproduce the crash neither on my 32 nor the 64 bit system... so I am quite unable to help. Has anyone explored the possibility of a corrupted/wrong wacom.ko in the distribution media?
