I also discovered system freeze on my Thinkpad T61p since Ubuntu 9.4. I already tried to report the behaviour in https://bugs.launchpad.net/ubuntu/+bug/391085. Maybe it was not clear enough, sorry for my poor English.
I could some how catch some error according to the kernel bug: Jul 21 01:23:33 beyond-laptop kernel: [ 6676.977905] ------------[ cut here ]------------ Jul 21 01:23:33 beyond-laptop kernel: [ 6676.977914] kernel BUG at /build/buildd/linux-2.6.28/mm/slub.c:2743! I attach the error.txt file which contains the whole log excerpt and the file requested in #5. The freezing happens when my Thinkpad is on the docking station. I hope it helps to help me/us. thanx, cue ** Attachment added: "kernelbug.txt" http://launchpadlibrarian.net/29792607/kernelbug.txt -- 2.6.28-11:ext4:hald:sys_open:security_file_alloc -> cascade of 'bugs' -> CPU stopped https://bugs.launchpad.net/bugs/348731 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
