Summary | 0014399: Kernel Deadlock | ||||
Description | The recent kernel (Version 3.10.0-693.11.6) with revoked microcode updates (active is Intel Microcode Version Ref. 0x3a 2017-01-30 for Haswell EP CPU, with activated PTI) has produced a kernel deadlock situation (10 of 12 threads blocked, 1x Haswell E5-2620 v3 with Hyperthreading) during heavy fileserver usage (NFSv3 and rsyncd). The storage is based on mdraid,lvm and ext4 with a HBA Controller (LSI3008 chipset). Details see in the attached kernel traces. After this problem occurs, the storage access was blocked and the system had to be rebooted. This setup was running with this fileserver load for the first time. The system was running stable with the same kernel and the microcode version ref. 0x3b (2017-11-17) for several days (12days). | ||||

The problem is happening randomly since reported in January. Also with Centos 7.5.1804. I have also KVM/libvirt running and therefore it could be related to this bug https://bugs.centos.org/view.php?id=13887. |
