[Kernel-packages] [Bug 1939996] Re: kernel BUG at mm/zswap.c:1275
I can reproduce the bug on -22 and -25 kernels. Here are almost full dmesg logs. You can see SSD errors where swap is placed. This issue may be related to them somehow. To exclude hardware element of errors, I will try other more recent laptop or VirtualBox. Steps: 1. sudo mount -t tmpfs -o mode=775 tmpfs /mnt 2. sudo dd if=/dev/urandom of=/mnt/garbage Wait till ENOSPC. In my case, the garbage file becomes of 8 GB. 3. ./eatmem 500 This hand-made program only consumes a lot of memory in a loop then sleeps. So I speculate when the kernel wants to displace tmpfs content to a swap, it encounters the bug. If I reverse second and third steps, the bug does not appear. ** Attachment added: "dmesg_0846.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1939996/+attachment/5518106/+files/dmesg_0846.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/1939996 Title: kernel BUG at mm/zswap.c:1275 Status in linux package in Ubuntu: New Bug description: I have just found the following lines in dmesg.
