View Full Version : Kernel Update broke wake from lirc

I have a mediacenter usb remote (mceusb) that I use to operate my mythbuntu box. I set it up to suspend to ram via the power button using the instructions here:

http://www.mythtv.org/wiki/MCE_Remote#S3_.2F_Suspend_To_RAM

Basically it involves enabling wake from USB in /proc/acpi/wakeup, running irexec, and configuring lirc to call irexec with the hibernate command. It works great. Or it did work, until I applied the recent update to kernel version 2.6.32-23. Then it stopped waking up. It would still hibernate just fine when running, but I could only wake it up by pressing the power button. When in hibernate mode, the IR receiver just appears to be dead, its light doesn't even blink when I press buttons on the remote, like it's not even getting any power.

I rebooted into the older kernel (2.6.32-22), and lo and behold it worked great again. I've since uninstalled the updated kernel and this is a fine work-around for me. I have no reason to really need the updated kernel. However, I wanted to report this to whoever the right person or group might be. I wasn't sure who that was though, so I started here. If this is not the right place to report the issue, can someone redirect me? Thanks.

Just thought I'd pipe in and let you know you're not the only one affected by this issue. :smile:
