Package: linux-image-3.16.0-4-amd64 Version: 3.16.43-2 Hi!
After upgrade kernel to 3.16.43-2 version I have faced with strange bug that never seen before in Debian. My server became unresponsive after couple hours after boot. Couple times I saw error «BUG: soft lockup - CPU#0 stuck for 22s!» that I see on the console. Server became to normal work only when I unplug power cord from the server and plug it back after 10-20 seconds. This bug appears randomly and not depend from software that I’m using or from additional hardware that I connecting to the server (for example, I have installed GPU and bug still present). Also I have tested two kernels from back ports. They are listed below: Package: linux-image-4.9.0-0.bpo.2-amd64 Version: 4.9.18-1~bpo8+1 Package: linux-image-4.9.0-0.bpo.3-amd64 Version: 4.9.25-1~bpo8+1 On those two kernels bug reproducing well on my peace of hardware. After a month of suffering I was forced to roll back to stable kernel version that works well without any issues: Package: linux-image-3.16.0-4-amd64 Version: 3.16.39-1+deb8u2 I’m using Hewlett Packard ProLiant MicroServer G7 N40L. If you will have additional questions or need more information please let me know. Please, advice. Thanks, Serhiy
