Since the entire (second) sequence finished without error, I am operating on the assumption that this is not a result of me shooting myself in the foot. After installing world of a few days ago, both new and old kernels will spew out spurts of the following on the console: acpi: bad read from port 0x086 (8) acpi: bad write to port 0x086 (8), val 0 acpi: bad read from port 0x086 (8) acpi: bad write to port 0x086 (8), val 0 acpi: bad read from port 0x086 (8) acpi: bad write to port 0x086 (8), val 0 acpi: bad read from port 0x086 (8) acpi: bad write to port 0x086 (8), val 0 acpi: bad read from port 0x086 (8) acpi: bad write to port 0x086 (8), val 0 acpi: bad read from port 0x086 (8) acpi: bad write to port 0x086 (8), val 0 acpi: bad read from port 0x086 (8) acpi: bad write to port 0x086 (8), val 0 acpi: bad read from port 0x086 (8) acpi: bad write to port 0x086 (8), val 0 acpi: bad read from port 0x086 (8) acpi: bad write to port 0x086 (8), val 0 acpi: bad read from port 0x086 (8) acpi: bad write to port 0x086 (8), val 0 acpi: bad read from port 0x086 (8) ... I seem to recall there being an off-by-one error for someone else, but that was port 83, IIRC (I can't seem to find the commit message for that fix at the moment). Does anyone have any thoughts about this? An incomplete (non-verbose) dmesg and pciconf may be found at: https://netfiles.uiuc.edu/kaduk/www/prolepsis/ (sorry that it thinks the dmesg is a binary file) Thanks, Ben Kaduk
