It goes back to at least 4.0 - that's the oldest kernel I had laying around precompiled. The messages about ROM signature changed somewehere between 4.0 and 4.7 (4.7 is already like 4.13) but after some time, the same vmalloc errors appear. Maybe the userspace has changed with more respawning that brings the problem out. I tried to read the code but I do not understand it yet. The warning seems to come from generic pci_map_rom() checking ROM size, and returning rom pointer to aty128fb (it returns resource size too but that is ignored). aty128fb starts to look at the x86 PCI ROM signature again but does not tell that the signature is missing. How come? -- Meelis Roos (mroos@linux.ee)
