I just got a new HP z840 - dual E5-2667 v4 CPUs. After installing our company's official Red Hat Enterprise Linux 6.7 64-bit image, it throws a kernel panic during boot. This happens with installed RHEL 6.7 and via a live DVD/USB CentOS 6.7 and CentOS 6.8. HP lists RHEL 6 as a supported operating system.
I tried adding the boot option nomodeset, no help. When installing RHEL 6.7 via kickstart I gave the dd option to include the HP provided driver disc for RHEL 6.7 but it said the driver disc was incorrect; I also tried downloading it from HP and providing that instead; no luck.
A live DVD/USB of Ubuntu 16.04 or CentOS 7.3 boot successfully.
Kernel panic - not syncing: Attempted to kill init!
Pid: 1, comm: init Not tainted 2.6.32-573.el6.x86_64 #1
panic [hex addresses omitted]
drm_kms_helper: panic occurred, switching back to text console
Verify the reason behind deletion of swap device while it was in use. In some cases it is also observed that underlying devices used for swap filesystem are not deleted from system, but it is having large number of IO errors, due to which the read IO on swap filesystem fails and results in same panic as described here. In such case as well, it would be recommended to please investigate why the IO on underlying disk devices were failing? Root Cause The kernel evoked panic() function because "init" task with PID (1) received a "SIGBUS" (7) signal due to "BUS_ADRERR". A "SIGBUS" can be caused by any general device fault that the computer detects, though a bus error rarely means that the computer hardware is physically broken. Bus error may also be raised for certain other paging errors. In this example "init" task with PID (1) received a "SIGBUS" (7) signal because of the deletion of swap device while it was in use.
