Darrick,

In our 2u asterisk servers running  with digium cards installed 1,2 or 4
port, we see ACPI errors like below:

ACPI Exception: AE_AML_INFINITE_LOOP, while evaluating GPE method [_L00]
(20100428/evgpe-395)
ACPI Error (psparse-0537): Method parse/execution failed
[\_SB_.PCI0.LPC_.SMBR] (Node dec31ef0), AE_AML_INFINITE_LOOP
ACPI Error (psparse-0537): Method parse/execution failed
[\_SB_.PCI0.LPC_.INIT] (Node dec31f04), AE_AML_INFINITE_LOOP
ACPI Error (psparse-0537):

We are seeing these errors on the smaller astlinux box, so I wanted to turn
off the ACPI function as this corrected the issues on our other asterisk
servers.

Calls get dropped and we see Dchan errors in asterisk console.

chan_dahdi.c:3160 my_handle_dchan_exception: PRI got event: HDLC Bad FCS
(8) on D-channel of span 1

Anything else let me know.

Thx for all the help/effort.

Lach
