@Talat, there was not specific fix that I know of. However, 4.8.0-27 had the 4.8.1 upstream stable updates applied. The fix may have come in from upstream with these updates. I'll mark this bug as "Incomplete" for now. Just change the status back to "Confirmed" if the bug re-appears. -- 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/1634862 Title: PPC + kernel 4.8 swap_dup: Bad swap file entry 2c16ed28 Status in linux package in Ubuntu: In Progress Status in linux source package in Yakkety: In Progress Bug description: Hi on ppc machines with Ubuntu 16.10 (Yakkety Yak), after upgrading to last Ubuntu kernel (4.8), and running installation of MLNX_OFED Driver package that run a compilation jobs that equal to number of CPUs , the System hangs and we got a bad swap file message with pages and pages of the following showing, this is just a sample from the system log.

I'd like to perform a bisect to figure out what commit caused this regression. We need to identify the earliest kernel where the issue started happening as well as the latest kernel that did not have this issue. Can you test the following kernels and report back? We are looking for the first kernel version that exhibits this bug: 4.5 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.5-wily/ 4.6 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.6-yakkety/ 4.7 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7/ 4.8-rc1: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8-rc1/ You don't have to test every kernel, just up until the kernel that first has this bug.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.9 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.
