[Bug 1886277] Re: unable to handle page fault in mempool_alloc_slab
Please ignore "Repeat to "make -j`nproc` deb-pkg" until you find the offending commit." it's the other way to build a kernel. Please install newly build kernel package, reboot and test. Then continue the process with `git bisect good` or `git bisect bad`. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1886277 Title: unable to handle page fault in mempool_alloc_slab To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1886277/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1886277] Re: unable to handle page fault in mempool_alloc_slab
I tried bisecting the kernel as described in #22. However, I used the URL git://git.launchpad.net/~ubuntu- kernel/ubuntu/+source/linux/+git/focal instead of git://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/bionic, I hope that's correct. The fakeroot command works and builds the kernel. However, doing make later fails with: *** *** Configuration file ".config" not found! *** *** Please run some configurator (e.g. "make oldconfig" or *** "make menuconfig" or "make xconfig"). *** make: *** [Makefile:695: .config] Error 1 I don't know how to go from here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1886277 Title: unable to handle page fault in mempool_alloc_slab To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1886277/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I also have this problem, which I reported as a new bug 1886775 which is probably just a duplicate of this bug. Same issue, -40 dies with NFS with similar stack trace and similar timing, -39 is fine, and multiple hardware has the identical issues. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1886277 Title: unable to handle page fault in mempool_alloc_slab To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1886277/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1886277] Re: unable to handle page fault in mempool_alloc_slab
Is there a tutorial available on how to bisect the kernel and install and test the bisected version? To me it seems the problem only occurs in connection with NFS. I could not reproduce the problem when NFS is not used. However, after reading data from NFS mounts the problem reliably occurs within a few minutes.
