Hi,
I am using linux 2.6.27.5 with em28xx-new and I get some slab corruption. I
applied some debug patch to em28xx-new and to the linux tree also (attached).
I enabled the some debug options in the kernel, like:
- CONFIG_DEBUG_OBJECTS_FREE=y,
- CONFIG_DEBUG_OBJECTS_TIMERS=y,
- CONFIG_DEBUG_SLAB=y,
- CONFIG_DEBUG_SLAB_LEAK=y,
- CONFIG_DEBUG_BUGVERBOSE=y
Steps to reproduce:
1. Plug Pinnacle Hybrid Pro Stick (320e)
2. Start kaffeine and start watching a digital channel
3. While kaffeine is running unplug the device
4. Now close kaffeine
Current result:

I could reproduce this 3 times out of 5 tries.
What the debug messages tells me is that the last executed checkpoint
was right before the
fe->ops.ts_bus_ctrl(fe, 0);
line in dvb_frontend_release() function. More I couldn't find out, yet.
