I'm not excited about maintaining maintaining linux-as-a-firmware-diagnostic -- particularly when... 1. it clutters the code for normail machines 2. finding the bug is pointless, because even if you fix one machine, you are guaranteed to not fix all machines and thus must maintain the workaround anyway. >> I'd also like HARDWARE_BUG_ON(), with similar usage. >> >> With all the preload-linux-on-foo project, we have some >> chance to make >> BIOS vendors fix their stuff if we can easily diagnose errors in >> there. These customers should be running http://linuxfirmwarekit.org/ We do maintain some degree of "high-road ACPI spec checking" with the "acpi=strict" boot option. If we do more of this, I think it should stay under that option. thanks, -Len -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
