Description: Illegal instruction called when using RTX2080Ti


Additional info:
* From journalctl: NVRM: Xid (PCI:0000:67:00): 31, Ch 00000010, intr 00000000. MMU Fault: ENGINE GRAPHICS GPCCLIENT_T1_3 faulted @ 0x7f1e_58b87000. Fault is of type FAULT_PDE ACCESS_TYPE_VIRT_WRITE
* The RTX2080Ti uses compute capability 7.5. Looking at PKGBUILD file it seems to be missing


Steps to reproduce:
Run maskrcnn-benchmark training on RTX2080Ti.
This task depends upon

PKGBUILD does have 7.5 compute capability included. This must be something else. Moreover, it doesn't seem to be due to pytorch, possibly cuda itself.

Does it crash or just throws an error, but completes. Please give more details in order to reproduce. Thanks.

Could you try glibc-2.28-6 in [testing] and cuda-10.1.105-8 in [community-testing] and see if it works?

If you give me a test file and a command, I'll try to reproduce. I got the same GPU.
