During the automatic installation I prepared for another host the whole system freezes right after the main package installation. Shutting down the machine manually with pressing the powerbutton, and booting it normally, helped a little. So this problem occurs with the default kernel as well. Marking as duplicate of bug #568120. *** This bug has been marked as a duplicate of bug 568120 *** |
Created attachment 336391 [details] Output of dmesg User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1.6) Gecko/20091201 SUSE/3.5.6-1.1.1 Firefox/3.5.6 While the system is booting several messages are shown like: "BUG: scheduling while atomic: swapper/0/0x10000002" Followed by kernel stack trace. After the system is booted everything looks ok, the swapper seems to be working fine nevertheless. Reproducible: Always Steps to Reproduce: 1. Install kernel 2.6.31.8-0.1-desktop 2. Reboot the machine 3. Run dmesg to see what happened after unpacking the initrd. Actual Results: [ 0.169806] Unpacking initramfs...
