One is when I leave laptop idle for some time (few hours?): http://people.freebsd.org/~pjd/misc/acpi_idle_panic_0.jpg http://people.freebsd.org/~pjd/misc/acpi_idle_panic_1.jpg And when is when I boot laptop without power connected and I connect the power: http://people.freebsd.org/~pjd/misc/acpi_power_connect_panic_0.jpg http://people.freebsd.org/~pjd/misc/acpi_power_connect_panic_1.jpg BTW. On the acpi_power_connect_panic_0.JPG photo, at the top of the screen you can see error messages that are logged every second when I have power disconnected. This is not a new problem. I had this problem when I bought this laptop, but now that I'm reporting those bugs, I can as well let you know about this one. I'm running this on Thinkpad T530. I understand that those problems are specific to my laptop and that on your laptop all of the above work just fine? --=20 Pawel Jakub Dawidek http://www.wheelsystems.com FreeBSD committer http://www.FreeBSD.org Am I Evil?
