I have had none of the APIC error on CPU0: 40(40) messages in my dmesg log since my last posting. However, I did continue to get the crashes more and more frequently (the blinking caps lock light). I had installed kdm, and was running the kde desktop sometime before all this happened. One day, after I decided to run GNOME, and I did not have the problems. However, due to a problem, that I am not sure about, I could not reconfigure GDM to be my default desktop manager (there are numerous postings about this, such as http://ircarchive.info/kubuntu/2007/3/18/124.html ), where I get the invoke-rc.d: initscript gdm, action "reload" failed. message, and even if I double checked that sudo dpkg --configure kdm or gdm was good. Anyhow, I no longer get the crashes, so I believe the issue for me, with the blinking caps lock light where my computer freezes, was associated with the KDE desktop somehow. Since I had complete freezes, and it could not log the error in dmesg, I have no idea where the crash was coming from. Since I reinstalled Ubuntu, and have not reinstalled KDE, I have had no problems whatsoever with either the CPU0: 40(40) flood or the blinking caps lock crash. Please note that both bennyatc and I have AMD64 Athlon CPU's, and we both have ATI Radeon Mobility Video cards (although his is a X700 and mine is a Xpress 200M). I'm sorry I cannot give more specific information as to what exact program was causing the crashes.
Thank you very much for the assistance you have provided thus far. Since I reinstalled, everything is quite stable. I just wanted to give some feedback on what could be causing the bug. -- APIC error on CPU0: 40(40) followeb by CAPS LOCK LED STARTS BLINKING AND THE NOTEBOOK CRASH https://bugs.launchpad.net/bugs/129500 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
