Summary0010176: kernel crashes on boot
DescriptionKernel crash on boot with HP ProLiant Microserver N36L + software raid 5

The last message I am able to see is "Swtiching to clocksource hpet"

Once, I saw the message:
Kernel panic - not syncing: Watchdog detected hard LOCKUP on cpu

On the last two occasions, I was presented with the following two backtraces:
Steps To Reproducekernel-3.10.0-327.4.4.el7.x86_64 crashes
kernel-3.10.0-327.3.1.el7.x86_64 crashes

kernel-3.10.0-229.20.1.el7.x86_64 is the last kernel that worked for me
Additional InformationThe issue seems similar to https://bugs.centos.org/view.php?id=9940 at first glance, however kernel-3.10.0-327.4.4.el7.x86_64 doesn't resolve the problem, so it may very well be a completely different problem.

I have also tried adding the debug option to the kernel command line, but it didn't improve the situation as was mentioned in https://bugs.centos.org/view.php?id=9940 .

My system employs a soft-RAID1 mirror for swap and /boot, and / resides on a soft-RAID5 array.

TagsNo tags attached.

Let me know if I can help with further debugging the issue.

I'm experiencing the same issue (CentOS Linux release 7.2.1511 (Core)
). When I use the 3.10.0-229.14.1.el7.x86_64 image then CentOS works.


clinton.fray (reporter)

Just an additional observation: I'm using the HP Proliant MicroServer N40L

probably related to https://bugs.centos.org/view.php?id=9860

What kind of CPU does your N36L and N40L have?


clinton.fray (reporter)

CPU: AMD Turion(tm) II Neo N40L Dual-Core Processor. I've checked the link you provided, yes it could be related. Thank you.

The Microserver N36L has the following CPU:

I have verifed that adding the "initcall_blacklist=clocksource_done_booting" string to the kernel command line works around the issue, thus this bug is a duplicate of https://bugs.centos.org/view.php?id=9860

thanks for confirming :)


nroskam (reporter)

I can also confirm that adding "initcall_blacklist=clocksource_done_booting" string to the grub profile and re-making the grub.cfg has finally resolved my booting issues with the latest kernels.

The last kernel that worked for me without this boot parameter was 3.10.0-229.14.1 on my HP N54L microserver. Now I run the latest 3.10.0-327.4.4 without problem.

Resolved. Please see bug #9860 for details.
