https://github.com/torvalds/linux/commit/2c012a4ad1a2cd3fb5a0f9307b9d219f84eda1fa It appeared in kernel 5.3 and was backported to 4.19.62 and Ubuntu kernel 4.15.0-59 (In reply to ValdikSS from comment #53) > Recently, about since kernel 5.2.7, the issue is either gone or present to > much less extent. > Right now I'm running kernel 5.2.11 and finally I can keel Firefox and > VirtualBox running at the same time, with 3G+ in swap, and the system does > not freeze. ... and to 5.2.3 But that commit "fixes" commits from the era of kernels 3.8 and 3.9, so probably it is not the one I'm looking for. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1833281 Title: System freeze when memory is put on SWAP in Linux >4.10.x To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1833281/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
