I compiled 2.6.13-rc4 with ACPI debugging enabled.

During a failed boot, when the keyboard was unresponsive, I managed
to capture a kernel log of this failure. Here are the lines that caught
my attention:

kernel: i8042.c: Can't read CTR while initializing i8042.
kernel: Serial: 8250/16550 driver $Revision: 1.90 $ 4 ports, IRQ sharing disabled
kernel: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
kernel: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A
kernel: ACPI: PCI Interrupt 0000:02:0a.0[A] -> GSI 22 (level, low) -> IRQ 16
kernel: ttyS2 at I/O 0xb800 (irq = 16) is a 16550A

This error/warning message does not occur all the time, but it
has appeared at least twice during my brief experimentation and
I would consider it something that can be duplicated.

So far it is the only anomoly that I have seen anywhere, but it may
be more a result of the problem rather than the cause.
