Date: Wed, 02 Nov 2011 12:12:29 +1300 [thread overview]
Message-ID: <7377461.xUP08Ft1Zz@linux-9am5.site> (raw)
Hello all
OS Information
OS: Linux 3.1.0-rc9-1-desktop x86_64
System: openSUSE 12.1 RC 1 (x86_64)
KDE: 4.7.2 (4.7.2)
Hardware Information
Lenovo Thinkpad L420 Model number 78544KM
i5-2520M(2.50GHz)
Intel HD Graphics
Problem
Fails to boot without boot option of either acpi=off, nosmp, or maxcpus=0
Almost immediately freezes. CapsLock does not work and only way to continue is
to power off with the power button.
With debug on last line of output reads:
ACPI: CE: Look up EC in DSDT
Fails with kernel 3.04 and 3.1 and all distro's I have tried with.
Boots no problem with 32bit and with Windows 7

Please let me know what other information I should provide.
Thank you
Regards
Steve
