Hi Harshit,
> 1. Is this reproducible on MAINLINE 6.18 ?
I can't test that, as I am using ZFS-on-root and ZOL currently supports
only up to 6.17.

I have bisected it to (first bad commit):
commit ded77c1209169bd40996caf5c5dfe1a228a587ab drm/amd/display: Fix
pbn to kbps Conversion.
I've CC'd the author & signed-off folks to the thread.
thanks,

Hi Harshit,
sorry for the late reply (and replying privately at first),
I had to wait for the release.
Np!
Unexpectedly, this is NOT fixed, persisting in 6.12.61, same trace.
Sorry I guessed it based on the fixes that went into 6.12.61. Sorry
about the incorrect guess.
I don't know if this is a known issue then. Couple of thing I would
try is:
1. Is this reproducible on MAINLINE 6.18 ?
2. Can you bisect the cause between 6.12.59 and 6.12.60 ? (using git
bisect) - Documentation:
https://docs.kernel.org/admin-guide/bug-bisect.html
thanks,
Harshit

upgrading from 6.12.59 to 6.12.60 broke my USB4 (Dynabook
Thunderbolt 4 Dock)'s video output with my Framework 13 (AMD Ryzen

With two monitors plugged in, only one of them works, the other
(always the one on the 'video 2' output) remains blank (but
receives signal).
relevant dmesg [note: tainted by ZFS]
(full output at: https://gist.github.com/x-

Just a note:
This looks related to whats fixed in 6.12.61:

Try with 6.12.61 maybe ?
