[Kernel-packages] [Bug 1959685] Re: Kernel BUG with btrfs on linux 5.13
I'm now trying to run v5.15 kernel after months of v5.4 running without crashes on BTRFS. On first boot with v5.15 I've got on dmesg ... [ 63.021417] BTRFS warning (device sdb): block group 12481442611200 has wrong amount of free space [ 63.021424] BTRFS warning (device sdb): failed to load free space cache for block group 12481442611200, rebuilding it now ..., which I didn't get with either v5.11 or v5.13. Maybe this corruption was the problem that v5.4 ignored, and v5.11/v5.13 crashed on. Uptime with v5.15 is 2 days so far. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1959685 Title: Kernel BUG with btrfs on linux 5.13 Status in linux package in Ubuntu: Expired Bug description: I am hitting the below kernel oops every 2-5 days on my home server box.

[Kernel-packages] [Bug 1959685] Re: Kernel BUG with btrfs on linux 5.13
The kernel BUG also happens with 5.11.0-46 and 5.13.0-28 kernels. In 5.11 the location of the fault is different, but the symptoms are very similar to crash in 5.13. Attached are kern.log excerpts for 5.11.0-46 and 5.13.0-28 crashes. I'm now testing 5.4.0-99-generic. ** Attachment added: "kern2.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1959685/+attachment/5560158/+files/kern2.log -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1959685 Title: Kernel BUG with btrfs on linux 5.13 Status in linux package in Ubuntu: Incomplete Bug description: I am hitting the below kernel oops every 2-5 days on my home server box.
