"BUG: unable to handle kernel paging request at 0000000000002b20"


We have random crashes/reboots on our GPU-enabled RHEL7 servers. I believe it’s related to nvidia, but not 100% sure. Wondering if anyone else has experienced similar failures.

Thank you!



GeForce RTX 2080 Ti

Thanks for reporting this. It’s being tracked in internal bug number 3279571. The bug tracker is not public but you can refer to this number in future correspondence.

Hi @aplattner , I have the same issue as describe above on multiple Centos7 systems running the versions below

NVIDIA-SMI 465.19.01 Driver Version: 465.19.01 CUDA Version: 11.3
kernel 3.10.0-1160.6.1.el7.x86_64

Would it be possible to have an update on the bug 3279571 ? any workaround or is that fix in another release ?


I face the same problem on eulerosv2r7, Driver Version: 460.80, @aplattner does it fixed in another release?

Hi @aplattner We see this also and have for some time. At least 2080 RTI, RTX 6000, RTX 8000 and A6000 GPUs. Various driver versions, most recently 460.73.01. Centos= 3.10.0-1160.31.1.el7.x86_64 #1. Seen on different Supermicro systems.

Hi @aplattner, we are facing the same issue with driver ver. 460.73.01 or 460.32.03.

  1. RHEL 7.6 with Kernel v. 3.10.0-1160.31.1.el7.x86_64
  2. Driver ver. 460.73.01 or 460.32.03
  3. HPE XL270d
  4. Tesla V100 (8x GPU Cards)

We cant take the machines in production if we don’t have a fix. Delaying projects is no fun. Thanks.

Solution for me: I upgraded the system to RHEL 7.9 with 7.9 Kernel - 3.10.0-1160.31.1.el7.x86_64 and NVIDIA driver version 460.32.03 runs stable. 5 days now without crash. It is interesting that I didn’t get any help from NVIDIA (enterprise) because I don’t run a grid version and from HEP because this constellation is not supported.

Update: Problem not resolved… crashed after 5 days…

Any update about the bug: 3279571?

That bug should have been fixed in 470.94. Are you experiencing a crash? If so, please generate and attach a new bug report log.

We resolved our problem by enabling persistence mode. It may seem trivial, but we had absolutely no crashes with pm enabled (or using daemon), and as soon as pm was disabled, crashes showed up again. Re-enabled pm and no crashes for months now.

EDIT: Just to clarify, we saw crashes for months on several systems, but once we enabled pm, the crashes were gone on all systems. We disabled pm just to confirm our findings.
