Were those two vanilla kernels? I asked in #snappy on IRC and was
told
that "snapd simply expects some ubuntu bit in patched into the
kernel if
it detects that it runs on an official ubuntu install...". This
was also
suggested "it probably makes sense to file a but in LP to make the
kernel team aware".
Yes, last time I tried it with git clone from linux_stable on
kernel.org
and
config-6.0.0-060000-generic from the official Ubuntu mainline build
You don't want to do that. Better take the config used to build a
working kernel (say 5.19.y) and then build 6.0 with it (after running
"make olddefconfig"), because it might be a new kernel option (say
for a
new security technique) that might cause the problem, as explained
here:
https://docs.kernel.org/admin-guide/reporting-regressions.html
If I understood well, that would mean building www.kernel.org git
linux_stable
source with Ubuntu's config-5.9.13-051903?
I meant "please download Linux 6.0 (ideally through git, that you have
everything to perform a bisection), add the config from a working kernel
(if config-5.9.13-051903 is one, yeah, then take that) as .config and
then run "make olddefconfig" before compiling and installing the kernel
to see if 6.0 fails with that config that was working.
Hi, Thorsten,
Having done this build with mentioned config-5.19.13-051903-config from
Ubuntu's mainline build and your recommended make option
had produced a kernel that so far did not exhibit the Firefox snap
"tab crash/wrong Verneed record version" bug.
However, the uptime is 1d 18h50min, so it might be too early to draw
a definite general conclusion.
Now, the brave conlusion seems to be that the culprit is one of the
modules
added in config-6.0.0-060000-generic.
I am new to this, but is seems that we should look at some compiled-in
modules (147 loadable and 41 compiled-in):

However, I'm stuck on this. Disecting the modules to one that caused
the problem seems
infeasible, for it takes me two hours for a build ...
Hope this helps ...
I know that it is uncool to reply one's own email, but this is new
development:
After starting a zoom spawned session, the Firefox snap tab crash
reappeared.
I will reinstate that if was done with the config-5.19.13-generic and
"make olddefconfig"
followed by a "make -j 10 deb-pkg" build.
Here is the exact log of my actions:
