2.6.30 dmesg: i2c_i801 loads, causes 15 second delay in eeepc-laptop
This was raised when eeepc-laptop was reported to cause ~15 second delays on
bootup. We saw it before in Bug 12376. The cause is that i2c_i801 binds to
hardware which is also driven by the ACPI BIOS. Blacklisting i2c_i801 fixes
it.
In debian 2.6.29-something, "acpi_enforce_resources=strict" fixes the problem
by reserving the resources used by ACPI, so i2c_i801 can't bind.
2.6.30 should fix it because "strict" is now the default. But it doesn't work;
i2c_i801 is loaded even if the "strict" boot option is set. This is a
regression.
