Can you try with latest master ? Should be fixed with:
https://cgit.freedesktop.org/mesa/mesa/commit/?id=8cd71f399e73c5d87e9162cc74da76e317a9f41f
Sorry for the inconvenience

Tested both master and 8cd71f399e73c5d87e9162cc74da76e317a9f41f specifically,
but it still hangs and the stacktrace looks the same.
Any way I can help debug this?

So somehow the factoring is incorrect
https://cgit.freedesktop.org/mesa/mesa/commit/?id=1cec049d4db1c4dcd121bad17df4a77273dd9bb1

If you can log the values for offset and stride before and after this patch it
might help to understand the issue. Thx

Maybe I should have stated so explicitely,
ec6c2297634eba77248a929048cf4201887a5f0a is the first commit to crash. It looks
like it crashes even before calling si_texture_get_handle as there's nothing
logged on bad builds. Possibly there is something wrong with my setup? I'm only
compiling mesa from git, all other libs are from repos.

This one
https://cgit.freedesktop.org/mesa/mesa/commit/?id=ec6c2297634eba77248a929048cf4201887a5f0a
?

or
https://cgit.freedesktop.org/mesa/mesa/commit/?id=a3c202de0a963c0562796cf75e3a9b3eedf1afad
?

Any chance you can install the debug symbols ?

While trying to use the coredump, I've noticed /usr/lib64/dri/radeonsi_dri.so
was used, so I've tried checking Xorg process with lsof in the good build...
turns out both /usr/lib64/dri/radeonsi_dri.so and
/opt/mesa/lib64/dri/radeonsi_dri.so were listed. With bad builds, renaming
/usr/lib64/dri results in kde working but glxgears and glxinfo failing, while
symlinking it to opt makes everything fine.
So, looks like there's something wrong with my setup rather than mesa itself.
I'll keep investigating why this happens but I guess this is invalid anyway.
Sorry for the trouble.
