We verified the following proposed kernels: Xenial: 4.4.0.58.61 and 4.4.0.58.79 Yakkety: 4.8.0.34.43 Standard kdump and kdump through NMI work now as expected, single core and SMP configurations. ** Tags removed: verification-needed-xenial verification-needed-yakkety ** Tags added:

I also built a xenial test kernel with the patch. It can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1400319/xenial Can you see if this kernel also resolves the bug on 16.04? If it does, I'll SRU the path to both Xenial and Yakkety. -- You received this bug notification

I've tested the kernel on Ubuntu 16.04 32 bit and everything works fine, even with kdump through NMI. Note: Kdump through NMI on Ubuntu 16.04 32 bit with kernel 4.4.0-21-generic is not working. I've also tested Ubuntu 15.04 but this version is End of life. -- You received this bug notification

Hi Joe, We did look at http://kernel.ubuntu.com/~jsalisbury/lp1400319/ however that folder has the 32bit kernel and binaries. As this bug is in regards to the 32bit architecture, we would need the i386 kernel actually. Thank you! -- You received this bug notification because you are a member

A consideration: From: Vitaly Kuznetsov When we crash from NMI context (e.g. after NMI injection from host when 'sysctl -w kernel.unknown_nmi_panic=1' is set) we hit kernel BUG at mm/vmalloc.c:1530! as vfree() is denied. While the issue could be solved with in_nmi()

kdump crash feature on 32bit Xenial GA (kernel 4.4.0-21) does work most of the times. The issue here can be related to the CPU handling the crash, for which there is a set of patches. These would also cover the kdump triggered through NMI scenario. -- You received this bug notification because
