Lau, OK we've checked some likely causes with no success. I think we need to move this issue along to the Kernel Team.
However, we need to re-establish the baseline data for this bug report since the problem was originally reported under Feisty and you now appear to be using Hardy. The Kernel Team will need this. Can you supply the following information for your present system [Hardy]: 1. Please include the output of the command "uname -a" in your next response. 2. Please run the command "dmesg > dmesg.log" which includes the freeze point and attach the resulting file "dmesg.log" to this bug report. 3. Please run the command "sudo lspci -vvnn > lspci-vvnn.log" and attach the resulting file "lspci-vvnn.log" to this bug report. 4. Please run the command "sudo dmidecode > dmidecode.txt" and attach the resulting file "dmidecode.txt" to this bug report. Thanks. Note1: Point (2) above should include the freeze point. If you can get it to freeze again and then reboot the dmesg should contain the freeze point. Note2: Also, after a freeze & reboot can you check syslog and kernel.log to see if anything useful is recorded such as a kernel oops. Note3: Your TSSTcorpCD/DVDW TS-L632D optical drive still concerns me. Can you check & report the present firmware version [AS05, SC03, SC04, something else?] just to put our minds at ease. Thanks again. ** Also affects: linux-source-2.6.22 (Ubuntu) Importance: Undecided Status: New ** Changed in: linux-source-2.6.22 (Ubuntu) Status: New => Incomplete ** Also affects: linux-source-2.6.24 (Ubuntu) Importance: Undecided Status: New ** Changed in: linux (Ubuntu) Sourcepackagename: linux-source-2.6.24 => linux Status: New => Incomplete ** Also affects: linux-source-2.6.17 (Ubuntu) Importance: Undecided Status: New ** Changed in: linux-source-2.6.17 (Ubuntu) Status: New => Incomplete -- system locking up (forcing a hard reboot) https://bugs.launchpad.net/bugs/89362 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
