I did two more things. I ran Memtest86+ (v. 2.11) repeatedly on the machine, with no errors. Then I tried installing the 2.6.30-rc7 kernel (image-386, headers-all and headers-386) from http://kernel.ubuntu.com /~kernel-ppa/mainline/v2.6.30-rc7/) and the freezes and symptoms remain the same as with the Jaunty 2.6.28 kernel. I verified that I am booting the 2.6.30 kernel after installing it.
Is there anything else that is kernel-related to try? Could it be the Intel graphics drivers after all? What should I try here? This machine was fine with Intrepid, but now it is useless. -- Thinkpad T61 locks up / freezes randomly; no flashing caps lock light, mouse cursor can be moved https://bugs.launchpad.net/bugs/377194 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
