at least SOME of those hangs seem to be looking at sysfs. in the temp module -
did you select udev? if so - try switching to the default internal (under
hardware). i see at least 1 of the bt's with the mainloop stuck in a
udev/eeze call in a timer:

eeze_udev_syspath_get_sysattr
(syspath=0x181ed4c "/sys/devices/virtual/hwmon/hwmon0",
sysattr=0x7ffc4b553360 "temp1_input")

that is suspicious. i DO know that checking of /sys/proc devices from the
kernel CAN be slow - sometimes it blocks and hangs for many miliseconds (10's
even or 100's). i do not know if this is just bad kernel drivers or the
hardware literally is this slow.

anyway - this is why the "internal" temp fetcher (tempget binary) is a separate
process entirely which ONLY does one thing - sits and polls temperature sending
it back to e via stdout. then e doesnt block.

:) try this and see - or just disable temp module entirely and see.

Re: [e-users] Temporary display hangs

Thankyou :)

I think I have such an example now. I set up a keybinding to do the
killing, based on my observation that keyboard input and pretty much
everything else continues during one of these hangs. Here's what was

Re: [e-users] Temporary display hangs

Ping ...

I've now confirmed that these graphics hangs only occur under Enlightenment
- I used Gnome all day today and didn't have a single hang, whereas under E
I would have had 3 or 4 already. Also tested with a wider range of kernels
( vanilla, up to 4.2.4 ).

killall -SEGV enlightenment
