Possibly fixed with these patches? https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=15e8b95d5f7509e0b09289be8c422c459c9f0412 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=680174cfd1e1cea70a8f30ccb44d8fbdf996018e Thanks Alex, it seems that Linus merged those patches (just today) for the next -rc release, am I right? If so, I'll do a quick test and let you know as soon as Ubuntu team will release the next mainline kernel (usually just 1 or 2 days after -rc is out). (In reply to Felice Tufo from comment #2) > Thanks Alex, > it seems that Linus merged those patches (just today) for the next -rc > release, am I right? correct. I confirm that the fix solves the bug on kernel 5.12.0-rc3 (at least on my test system). Tested also on 5.11.7 |
