Created attachment 306392 [details] Archive with the crash logs Using 6.10-rc1, IOMMU causes graphics crash on this specific machine with AMD A8-7650K (KAVERI) iGPU. 6.9.x was fine. Happens only if IOMMU is enabled in UEFI. It starts with such messages: iommu ivhd0: AMD-Vi: Event logged [ILLEGAL_DEV_TABLE_ENTRY device=0000:00:01.0 pasid=0x00000 address=0x10131a880 flags=0x0080] AMD-Vi: DTE[0]: 7490000000000003 AMD-Vi: DTE[1]: 00001001016a0002 AMD-Vi: DTE[2]: 20000001041f8813 AMD-Vi: DTE[3]: 0000000000000000 ...

Not my area of expertise, but what you describe looks a bit like the symptoms in existing reports that will be fixed by this patch https://lore.kernel.org/all/20240530084801.10758-1-vasant.hegde@amd.com/ (that with a bit of luck might make it into 6.10-rc3)
Right. Above patch and another path to fix EFR issue [1] should fix this issue. [1] https://lore.kernel.org/all/20240530071118.10297-1-vasant.hegde@amd.com/ Note that all these patches are in Joerg's fix branch. as THorsten mentioned hopefully it will make it into -rc3. -Vasant
Thanks. I also thought about https://lore.kernel.org/lkml/ZlweciPk77ra9W7H@gmail.com/ being related, but did not test that machine with rc2 yet. I could apply the aforementioned patches ahead of time to test them though.
But this report turns out to be a duplicate though. The other one is more detailed. So I close this anyway. *** This bug has been marked as a duplicate of bug 218900 ***
