If there is something that used to work with an Ubuntu kernel and stops wor= king there, you might want to report it to the Ubuntu developers, but not here. This bug tracker care mainly about upstream kernel (see front page), so what happens with a kernel build from the Ubuntu sources (which are known to be modified a lot) is irrelevant and even just mentioning that makes things ha= rd to follow. :-/ Regarding your problem: I'm not familiar with the code that might cause thi= s, but to me it looks a lot like Ubuntu switched on a kernel configuration opt= ion that is causing this. If that's the case the problem doesn't qualify as regression, as explained here: https://www.kernel.org/doc/html/latest/admin-guide/reporting-issues.html The developers nevertheless might be interested in fixing this, but might n= eed more details from you (like the config option that is causing this) --=20 You may reply to this email to add a comment.
