Summary: "ACPI: EC: missing confirmations, switch off interrupt
mode" on startup on 2.6.29 kernel
Product: ACPI
Version: 2.5
Kernel Version: 2.6.29
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: EC
AssignedTo: [email protected]
ReportedBy: [email protected]
Regression: No
My netbook (acer aspire one 110) consistently shows during boot the message
ACPI: EC: missing confirmations, switch off interrupt mode
> [ 0.351161] calling acpi_init+0x0/0x236 @ 1
> [ 0.361052] ACPI: EC: Look up EC in DSDT
> [ 0.367754] ACPI: BIOS _OSI(Linux) query ignored
> [ 0.368984] ACPI: EC: non-query interrupt received, switching to
> interrupt mode
> [ 0.860013] ACPI: EC: missing confirmations, switch off interrupt mode.
> [ 0.866062] ACPI: Interpreter enabled
I can't say if this is a regression, since this is a new hardware, and I didn't
install any previous kernel.
I attached full dmesg obtained after #defining DEBUG in ec.c, and booting
kernel with initcall_debug.
