Details

Description:
Since kernel 2.6.24 system locks on boot if ac adapter is plugged in. If no ac adapter is present system boots as usual. Using a kernel below 2.6.24, or booting with acpi=off <-- which is not an option as notebook user also fixes the problem.

Uncompressing Linux... Ok, booting the kernel.
ACPI: EC: acpi_ec_wait timeout, status = 0, expect_event = 1
ACPI: EC: read timeout, command = 128

Using a Sony Vaio VGN-C2Z

Additional info:
* package version(s)
* config and/or log files etc.
kernel26-arch

Steps to reproduce:
Boot a Sony Vaio VGN-C2Z with current kernel26 and ac adapter plugged in.
