In drivers/gpu/drm/i915/display/intel_dpll_mgr.c, I see an entry for 540,000.
Presumbly, this clock was supposed to be rounded up to that somewhere.
This is an HP Spectre x360 using the internal display. Here's the EDID
in case that's useful:

I tried -rc2, which contains that commit, and the problem is gone. Thank
you!
There is a different problem, which is that the brightness buttons
(on F2 and F3 on this laptop) do not actually increase/decrease the
brightness. GNOME pops up a graphic that illustrates it is changing
the brightness, but nothing actually changes.
xbacklight says "No outputs have backlight property" and using
xrandr --output XWAYLAND0 --brightness 0.0001 doesn't change anything
(for various different values, not just 0.0001). Using xrandr --prop
--verbose shows the reported value of "Brightness" changing, but nothing
has changed on the screen.
I found
/sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-eDP-1/intel_backlight
and tried setting 'brightness' in there to a few different values (100,
2000, 19200, 7000) and also nothing changed.
Any thoughts?

Thanks for testing it, I'll send a patch for the 5.10 stable tree as
well.

One possibility is that from the different backlight methods (DPCD,
direct PWM on a CPU pin) the driver selects the incorrect one. Could you
provide a log booting with drm.debug=0x1e adding it to a new ticket at
https://gitlab.freedesktop.org/drm/intel/-/issues/new?issue
or at least in a reply to this thread?
Adding Jani for further ideas.

Please try:
1) i915.enable_dpcd_backlight=1 module param
2) https://cgit.freedesktop.org/drm/drm-tip drm-tip branch with patches
from Lyude on top https://patchwork.freedesktop.org/series/81702/
BR,
Jani.
