Thanks. I see the same behavior (i.e. no warning) with the patch. I will add the patch 'commit f5451547b8310868f5b5acff7cd4aa7c0267edb3' to linux-nvidia-6.2 then.. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-nvidia-6.2 in

I built and tested a 6.2.0-1004-nvidia based kernel with this patch applied and did not see the warning message on boot. I'll follow up further with Ian on Monday. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-nvidia-6.2 in

Can you try the below commit from linus's "linux" tree and see if the warning goes away? commit f5451547b8310868f5b5acff7cd4aa7c0267edb3 Author: Thomas Gleixner Date: Tue Feb 7 15:16:53 2023 +0100 mm, slab/slub: Ensure kmem_cache_alloc_bulk() is available early -- You received this bug

yeah I suspect that.. there are couple of irq patches in the 6.2.0-1004-nvidia could be the cause.. I will update here shortly! -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-nvidia-6.2 in Ubuntu.

I ran through several kernels on our DGX-2 server, only the latest 6.2.0-1004-nvidia kernel emitted the warning. Here are all the kernels I tried: Lunar 6.2.0-24.24 generic - PASS Jammy 5.15.0-1028-nvidia - PASS Jammy 5.19.0-46-generic - PASS Jammy 5.19.0-1014-nvidia - PASS Jammy 6.2.0-25-generic
