Thanks again Bambang and Hans-Christian for the report, it seems indeed a bug in the kernel. I think I know what's going on, but I'd like to ask you to perform some testing in order we can prove that, and then fix it.
So, first it'll be 2 tests - depending on the result, a third test will be necessary. Please be sure to try both (1) and (2) with dos2emu using the KVM mode: (1) For the first test, please get the Bionic proposed kernel (see [0] for information on how to do it) - the current proposed version is 4.15.0-137. Try to reproduce with that version - I expect it to reproduce. (2) Now, get the build I made for you in https://kernel.ubuntu.com/~gpiccoli/lp1917138/ - observe that if you have the "linux-modules-extra" and "linux-headers" already installed on your system after test (1), please also install them from my build or else you might have issues in the boot process. To install the packages, download them from the link above to some directory and then run "dpkg -i *.deb" (supposing no other .deb file is present in that directory). Reboot the system after a successful installation and try to reproduce the issue - I suspect it won't reproduce, dosemu2 should work fine even in KVM mode. Thanks in advance, Guilherme [0] https://wiki.ubuntu.com/Testing/EnableProposed (don't forget to disable the proposed repository after your tests) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1917138 Title: kernel 4.15.0-136 causes dosemu2 with kvm freezes To manage notifications about this bug go to: https://bugs.launchpad.net/dosemu2/+bug/1917138/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
