Re: CentOS 7 - kernel: BUG: soft lockup - CPU#3 stuck for 23s! [rcuos/1:19]

I will say that our problem seems to have been fixed by upgrading the kernel to 3.10.0-514.10.2.el7.x86_64.
Which version are you running?

Re: CentOS 7 - kernel: BUG: soft lockup - CPU#3 stuck for 23s! [rcuos/1:19]

lspci tells me that 00:01.0 is a PCI bridge: 00:01.0 PCI bridge: Intel Corporation Xeon E5/Core i7 IIO PCI Express Root Port 1a (rev 07) And we have the onboard video controller (which is not in use) that appears to be behind that: 01:00.0 VGA compatible controller: NVIDIA Corporation GF119 [GeForce...

CentOS 7 - Attempted to yield the CPU while in atomic or interrupt context

We are seeing a similar error that does not seem to have any connection with I/O. We are getting the following on the console log: --cut here-- [256309.599704] NVRM: Xid (PCI:0000:01:00): 8, Channel 00000003 [256311.603743] NVRM: os_schedule: Attempted to yield the CPU while in atomic or interrupt c...

Re: CentOS 7 - kernel: BUG: soft lockup - CPU#3 stuck for 23s! [rcuos/1:19]

We're not doing much disk I/O at all, if anything we are mostly doing massive amounts of USB3 I/O to a camera. But again, never had the issue before the kernel upgrade.

Re: CentOS 7 - kernel: BUG: soft lockup - CPU#3 stuck for 23s! [rcuos/1:19]

We're seeing similar issues on Centos 7. No problem on 6.8, but upgrading to 7 with the 3.10.0-514.6.1.el7.x86_64 kernel and nvidia driver 375.39 gives us seemingly identical behaviour, running directly on real hardware. I think this is a new kernel bug, or else something related to an nvidia driver...
