Could please attach the output of 'acpidump' command.
Created attachment 8919 [details] acpidump output
Does booting with ec_intr=0 make any difference? If not - could you please boot with acpi_debug=0xffffffff to enable debug messages and submitt 'dmesg' output.
seems to work with ec_intr=0
The default value for ec_intr was changed from 0 to 1. So, I'm closing this bug. Please, re-open if the problem persist.
