[Bug 1780628] Re: linux-4.15.0-23-generic RAID 5 kernel BUG
I have a same problem with the current version of Ubuntu 18.04.1 LTS (Bionic Beaver) with kernel 4.15.0-42-generic. I have a new RAID 5 array with 4 12TB drives. As the array is being initialized, it takes 3 to 10 minutes to reach a kernel bug (under the additional system load less than 1 minute). ** Attachment added: "Call Trace" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1780628/+attachment/575/+files/trace.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1780628 Title: linux-4.15.0-23-generic RAID 5 kernel BUG To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1780628/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.18 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.
