Everything worked as well as it's going to for kernel versions up
through v5.10.0. When I boot on v5.11.0, "lightdm" starts, the screen
goes blank as usual, I get a mouse pointer as usual, and shortly after
that, the system locks up solid (completely nonresponsive except for
being able to ping it -- can't login remotely). Recovery is via the
reset switch at that point :-(.

Same results for 5.12.0-rc4 kernel.
I think the only feasible way of determining what has happened here is
that you track the offending change down by bisecting the upstream kernel repository with `git bisect'.

That would normally be what I would do, and it may yet happen. Problem
is, I don't have a 64-bit system with enough disk space to do the kernel builds with a cross-compiler, and local (native) builds on the PWS are
taking 36+ hours each these days. Unless I get *really* lucky with the bisects, the task will take a couple of weeks.

Confirmed that v5.11.0 hard locks up on presenting the X-Desktop
login screen whereas v5.10.0 is fine. This is on a XP1000 with
a Radeon HD4350.

and locks up hard when X is started on my Alpha XP1000.
Well *that* is rather interesting. We have considered dropping Alpha support because we couldn't find somebody with that hardware any more.
We're also supporting everything else that most commercial vendors consider obsolete
such as PA-RISC, M68k, big-endian PowerPC (32 and 64 bits) SPARC and so on, in case
you need testing there.

(Mostly including the above just as a reference to the most recent
posting in this thread...)
As of mainline kernel 5.12.0, the fix I (we) have been waiting for still hasn't been included. My alpha still locks up when X11 starts.
Stuck at kernel version 5.10.0 for the time being.
I have lost track about this issue, so please fill me in as to whether
the offending commit causing the regression has been bisected or not.

There were a few follow-up messages in this thread that left me with the impression there *may* have been a patch submitted, although Christian complained at the time he was having problems locating Alpha hardware to
test with.
The current (5.12.0 kernel) problem symptoms show some "improvement".
I at least got to the point that the login screen displayed, but it
had a bit of pixelation/distortion in a few areas indicative of "bad
things about to happen". Then I got the expected system lock-up,
just as I originally reported: had to hit the reset switch to recover.
Quick update: if this issue was ever fixed, the patch hasn't made it
into the mainline kernel as of 5.13.0. I'm still getting the system
lock-up when X11 starts, and have to hit the reset switch to recover.
For whatever it might be worth, the mainline 5.10.0 kernel continues
to work properly alongside all the user space changes in "sid" that
have happened since late last year.
Respectfully,
--Bob

I had intended to assist in testing with real hardware but there
are other issues due to the 5.10 kernel on Alpha that need fixing
first and I am working on that. I am hoping to come back to this
and can run some tests in the near future.
