That's, uh, surprising - is CONFIG_PNPACPI set?


not there:

[root@localhost linux-2.6.9]# grep PNPACPI .config
[root@localhost linux-2.6.9]#


Now that I am back at the office and looking at the kernel .config via make xconfig I see that 8250/16550 device discovery via ACPI namespace (SERIAL_8250_ACPI) is not enabled. Is is safe to assume that it should be (go ahead and groan, I probably would) anything else that should be included?

Hm. How old is this kernel? SERIAL_8250_ACPI was merged into SERIAL_8250_PNP a while back.

2.6.9-42 Latest Centos kernel.  Too old?
