Cold booted a Sony VAIO VGN-FE41E with Stefan's kernel. I had to remove the power cord to keep it from panic-ing (the stacktrace needs more than the whole screen so I can't see the messages in that case; I have no serial port to try serial console). With quiet option, this was displayed on screen: [ 13.849997] ACPI: EC: boot_ec created [ 13.862159] ACPI: EC: acpi_boot_ec_enable [ 14.360831] ACPI: EC: acpi_ec_wait timeout, status=0, expect_event=1 [ 14.360831] ACPI: EC: read timeout, command=128 Loading, please wait... [ 148.955486] BUG: soft lockup - CPU#1 stuck for 11s! [modprobe:1290] (repeats with different timestamps and hangs)
The dmesg of the next warm boot without the 'quiet' kernel option with the power present is attached. EC messages: [ 48.202845] ACPI: EC: boot_ec created [ 48.202910] ACPI: EC: Look up EC in DSDT [ 48.210325] ACPI: EC: acpi_boot_ec_enable [ 48.210738] ACPI: EC: non-query interrupt received, switching to interrupt mode [ 48.214017] ACPI: EC: acpi_boot_ec_enable success [ 48.232768] ACPI: EC: GPE = 0x17, I/O: command/status = 0x66, data = 0x62 [ 48.232838] ACPI: EC: driver started in interrupt mode Another successful boot had exactly the same EC messages. ** Attachment added: "dmesg_bug191137_01.log" http://launchpadlibrarian.net/15828619/dmesg_bug191137_01.log -- [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
