well I've got a little problem here.
I have a vaio laptop running ubuntu. I upgraded it from version 7.10 to 8.04 using the Update Manager.
I had no problem with installation, but now when I start the computer it remains freeze after the BIOS check...
I only get this message
[ 12.194676] ACPI: EC: acpi_ec_wait timeout, status = 0, expect_event = 1
[ 12.194722] ACPI: EC: read timeout, command = 128
If someone can help me please =]
