https://bugzilla.kernel.org/show_bug.cgi?id=212955 --- Comment #13 from Alan Stern (stern@xxxxxxxxxxxxxxxxxxx) --- THat commit you found, 51e6f07cb12e, cannot be the real culprit. Merge commits don't change any code (as a general rule). Something must have gone wrong with the bisection procedure. The way to test the result of a bisection is: First, check out the commit that the bisection identified, build it and boot that kernel, and verify that the problem occurs. Second, check out the commit's parent (or revert the commit), build and boot the resulting kernel, and verify that the problem does not occur. One thing you could do is get a list of commits affecting the snd-ua101 driver and try checking out and testing various ones, to find the first commit which exhibits the problem. -- You may reply to this email to add a comment.
