Vladimir - that doesn't surprise me! I got the "ec_intr" setting from Greg Kroah-Hartman's Linux Kernel in a Nutshell, kernel parameters. However, when I searched the source to find out what it does I find it doesn't exist!
The good news is 2.6.25-rc9 isn't affected so hopefully we can identify the commits that have changed the behaviour. Looks like we're back to the "quiet" option until then (or leaving AC unplugged/switched off). ** Summary changed: - [Hardy] ACPI Embedded Controller (EC) stops boot when kernel boot 'quiet' option is enabled + [Hardy] ACPI Embedded Controller (EC) stops boot when kernel boot 'quiet' option is enabled or AC power is connected -- [Hardy] ACPI Embedded Controller (EC) stops boot when kernel boot 'quiet' option is enabled or AC power is connected https://bugs.launchpad.net/bugs/191137 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
