| | Hello,
| |
| | current andy-tracking (c59a8bdc7ca4b5470ebc43dfc31ed1d3d23a7c6f) seems
| | to cause an interrupt storm for input2/3. Such that the system gets dead
| | slow and the syslog filled with input event debugs.
| |
| | 9402b27b2a497f8eeb72f6fe1045f2c5be800fe2 works fine.
| |
| | Any idea?
|
| I guess it can be to do with the level interrupt processing change from
| Balaji, or the GPIO fixes from Werner between those two?  Or maybe it is
| config changes from me if this is that dumb input event debugging thing
| come back again.
|
| Can you show what the system input event things look like?  I don't
| think we need an "interrupt storm" to explain the system being slow if
| in fact we're spewing 200 input event debugs a second to syslog.

That'll be it I think...

+CONFIG_INPUT_EVBUG=m

It made trouble before that some rootfs will insert this module if it
exists and then it spews for every service of 2 x 100Hz motion sensors.
~ I'll remove it from the configs, it got introduced again here

Thanks for the report, it's real nice getting the last working hash as
well :-)
