[Kernel-packages] [Bug 1244505] Re: Kernel oops - unable to handle kernel NULL pointer dereference; EIP is at input_event+0x23/0x70

2013-10-27 Thread James Henstridge
So, it looks like one big difference is that the hid-appleir driver didn't exist in the 3.8 kernel, and presumably LIRC was programming the chip directly before. So I guess either (a) the driver is broken, or (b) LIRC is still trying to program the chip directly, and manages to confuse hid-appleir

I tried out a test kernel from henrix at http://people.canonical.com/~henrix/lp1244505/v1/ which also exhibited an oops. The stack trace was a bit longer with the top of the oops scrolling off the screen, but it still contained the appleir_raw_event and key_down frames. I also tried disabling LIR

I've given the new kernel a try, and was no longer able to reproduce the crash. The hid-appleir driver seems to be correctly generating keypress events, and LIRC still seems to be able to access the raw hiddev device. This gives me double input in XBMC, but that is clearly a problem with my local

2013-10-24 Thread James Henstridge
Public bug reported: After upgrading to Ubuntu Saucy (32 bit), I am able to reliably reproduce a crash by pressing any button on the IR remote of a Mac Mini. The system is running XBMC and using LIRC to handle the remote. The system locks up on the first button press on the remote, and prints an

I've tried the 3.12-rc6-saucy kernel, and was able to reproduce the bug. On the first IR command from the remote, I get the same NULL pointer dereference in input_event with the next few call frames in the hid_appleir module. ** Tags added: kernel-bug-exists-upstream ** Changed in: linux (Ubuntu)
