I'm wondering if this is the same thing that affects the ASUS EeePC 701 4G I don't see the errors referring to ACPI at boot time, but a stock boot from LiveCD 8.04 release with an SDHC card in the slot fails at detecting the USB subsystem.
Removing the 'quiet' boot fails Removing 'quiet and splash' boot fails Removing the SD card allows booting Adding 'ec_intr=1' allows booting (only tried once though) on an installed system: Removing Card allows booting Removing 'quiet' allows booting default settings boot takes over 3 minutes to complete the boot. It pauses after CPU detection. I'm not sure it's quite the same but there is an air of similarity to it. I can attach ACPI details if you think it would be useful or relevant cheers :) -- [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
