On the machine where USB disc gets disconnected generally after two days uptime, we have disabled the USB power management and this problem didn't happen for cca 6 days uptime.
Following script has been added to the file /etc/rc.local for i in /sys/bus/usb/devices/*/power/level; do echo on > $i; done On following machines: 10.0.3.57 10.0.3.58 10.0.3.40 10.0.3.39 All these machines will be monitored, if usb disconnect problem occurs This is the command for checking usb power management setting: for i in /sys/bus/usb/devices/*/power/level; do echo $i; cat $i; done auto - means that power management is enabled on - means that usb will be always on (enabled) We don't know why this helps. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/701011 Title: [lucid] USB storage disconnects after certain period causing ext3 I/O errors and OOPS -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
