I booted with the various combinations of noapic and acpi=off, but no joy. Here's what happened on my system:
1) booting with "noapic acpi=off" System "froze" at login screen. (I'm running Kubuntu, so at KDM login screen.) After what occurred in some of the below options, I'm not sure if it was actually froze or if it was X going to ~100% CPU -- but basically unresponsive. 2) booting with "noapic" System booted fine, but no change in external USB drive access. 3) booting with "acpi=off" Same as 1). But I did find that I was able to log in to a virtual terminal, but couldn't restart KDM. 4) While trying to figure out why the "acpi=off" option seemed to hang the system on X. I turned off the acpid and acpi-support service daemons (disabled so they wouldn't start at boot). Then I was able to log into KDE with the "acpi=off" boot option, but X usage was still up around 97% CPU, so the system was basically unusable. So I never really got to the point of determining whether the "acpi=off" option made a difference for the USB hard drive access since the system was unresponsive (except the mouse still seemed to have good responsiveness). Thanks for the suggestions. And I'm willing to try others that might help identify the problem. -- USB Hard Drive Not Accessible https://bugs.launchpad.net/bugs/264789 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
