Some digging revealed that it was hanging in combios_parse_mmio_table() while parsing the ASIC INIT 3 table. Looking at the BIOS ROM for the card, it becomes obvious that there is no ASIC INIT 3 table in the BIOS. The code is just processing random garbage. No surprise it hangs! Why do I say that there is no ASIC INIT 3 table is the BIOS? This table is found through the MISC INFO table. The MISC INFO table can be found at offset 0x5e in the COMBIOS header. But the header is smaller than that. The COMBIOS header starts at offset 0x126. The standard PCI Data Structure (the bit that starts with 'PCIR') lives at offset 0x180. That means that the COMBIOS header can not be larger than 0x5a bytes and therefore cannot contain a MISC INFO table. I looked at a dozen or so BIOS images, some my own, some downloaded from: It is fairly obvious that the size of the COMBIOS header can be found at offset 0x6 of the header. Not sure if it is a 16-bit number or just an 8-bit number, but that doesn't really matter since the tables seems to be always smaller than 256 bytes. So I think combios_get_table_offset() should check if the requested table is present. This can be done by checking the offset against the size of the header. See the diff below. The diff is against the WIP OpenBSD codebase that roughly corresponds to Linux 3.8.13 at this point. But I don't think this bit of the code changed much since then.

But a bug report and a closer look at the wrpll table showed that we've supported port clocks up to 300MHz. With the new code to dynamically compute wrpll limits we should have no issues going up to the full 340 MHz range of hdmi 1.4, so let's just use that to fix this regression. That'll allow 4k over hdmi for free! v2: Drop the random hunk that somehow slipped in. v3: Cantiga has the original HDMI dotclock limit of 165MHz. And also patch up the mode filtering. To do so extract the dotclock limits into a little helper function. v4: Use 300MHz (from Bspec) instead of 340MHz (upper limit for hdmi 1.3), apparently hw is not required to be able to drive the highest dotclocks.
