I am willing to provide any information, or run any tests that would be helpful.

Gaming and rendering work well, but hardware acceleration is an issue.

Cheers,

Inferior 1 [process 58745] will be killed.

The crash happens during a memory mapping operation:

mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_SHARED, 4, 0x1682b1000) = 0x7fa10749a000
--- SIGBUS {si_signo=SIGBUS, si_code=BUS_ADRERR, si_addr=0x7fa10749a000} ---

The driver is trying to map GPU memory at address 0x7fa10749a000 but gets a BUS_ADRERR

So, I got it working. I needed:

To enable Resize Bar in my UEFI

install the intel-media-driver from the git hub at - commit e46f78c35dfd11d7d95addf7b0b68685a2010fae (HEAD, tag: intel-media-25.3.2)

I installed with the prefix /usr but that may be a coincidence

It works. The requirement of resize bar was hard to find.
