rpi-update'ing to the latest firmware (acf3b95a82bdecd28d95c7b294cf5d5a9c3ced31), I can get a hard crash (have to unplug the power to reset) using the official modetest:

modetest -s 89:4096x2160-60

much older versions of the firmware (January?) did not crash with this command, but the problem was also observed with the current firmware of last week (since rpi-update has no log I can't say which exact release that was).

modetest -s 89:4096x2160-50 works with the current firmware.
modetest -s 89:3840x2160-60 also works.

it's a shame because this new firmware is better otherwise - less tearing.

also, I'm getting this in dmesg:

seems like it doesn't always completely crash the hardware just lock the current DRM opening app. When it doesn't crash the hardware I was able to ssh in and check the log, and got this further detail:

[ 98.998235] [drm:drm_atomic_helper_wait_for_flip_done [drm_kms_helper]] ERROR [CRTC:87:crtc-0] flip_done timed out
[ 109.234774] [drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] ERROR [CRTC:87:crtc-0] flip_done timed out

in this situation killing the stuck app doesn't bring video back so a reboot is stilll required, but at least it's not a hard power cord pull.

tested with 922deae6d1ff141d53cf9e703ffecd6f994e9d4e (newest firmware), same problem.

All rpi-update releases are logged in https://github.com/Hexxeh/rpi-firmware/commits/master
You can also choose to checkout any specific one of those releases by using sudo rpi-update <commit hash> on the hashes from that repo.

If you could narrow down the release that causes the issue it would be useful.
48570ba was a rework of the I2C comms for the HDMI block, with a bug fix in 16e0bdd.
f2df2a6 reworks some of the core clock tree setup.
Those would be the two most likely candidates.

I went back to 8c2ba64b27a4b6a1dfcd114203c6309f766e2ef4 which I thought had been working perfectly, producing video output at 4096' but it seems my memory is wrong, as it runs but doesn't produce an image my tv can detect. it definitely doesn't lock up though. 3840' is fine (video output and no lock), in all these versions of the firmware.

There is definitely some kind of bug here as the locking up and dmesg stack traces reveal. But perhaps it has to do with something unusual about my TV (XBR43X800D) when trying to start up 4096'.

here's the regular suspects:

fyi I had a chance to test the latest firmware with another 4k tv (tcl 50S423) and it also hard crashes modetest and/or locks up the pi4 when I run modetest -s 89:4096x2160. So this isn't limited to one tv. here's the edid from this tv as well:

Add

core_freq=600
core_freq_min=600

to /boot/config.txt and selecting 4096x2160@60 works, no crashes (tested about 5x times). probably needs to be documented somewhere before it makes sense to call this one "closed".
