I'm just going to chime in, since it sounds similar to what I'm experiencing.
Occasionally - perhaps every two to four days, but irregularly - the ATA driver seems to lock up. The system stays up and running, but any command that has to be loaded from disk will give an error message (I/O error), dmesg reports tons of disk errors, and my termperature monitor fails to report the disk temperature. Regarding the last item, it's a script that runs 'hddtemp' regularly. Come to think of it, these problems started to occur when I started to track disk temperature. Hardy with 2.6.24-19, happened with at least the previous kernel, too. Hardware is a Dell D620. -- ATA exception upon starting smartd, breaking drive until next reboot https://bugs.launchpad.net/bugs/197892 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
