This may be unrelated, but my uevm has been freezing too, and that seems to have started after plugging in the hdmi cable again. I've had it running stable for weeks before, without a display connected. There has been some weirdness with the linux framebuffer console on these newer kernels anyway. On pyra hardware you get a black screen, on uevm the image jitters all over the place.
It might be worth checking if the freezes happen without a display driver or with no screen connected.
Just for the records, we have two reports that the igepv5 has (had) also some issue with warm reset and abe_dpll ("reboot").
a) one reported recently by forum PM to me:
Blacklisting snd_soc_omap_abe_twl6040 also solves the reboot issue on the igep.
I used the 4.19-rc5 mainline with only the omap2plus_defconfig, no option changed, GCC-8.2.0. I didn't touch my ARM boards for a long time (I'm on fpga now), now LPAE is broken, but maybe it's linked to the old u-boot.
b) an old mail from March 2016 by Tony Lindgren:
- Warm reset seems to fail on igepv5, the clk code seems
to be missing clk_prepare_enable() for the abe_dpll. I need to debug this more as it seems that with LPAE reboot is still flakey on igepv5. Looks like omap5-uevm does not have this issue, but it has a newer u-boot as well.
