I've had the same problem with hardy alpha 5. after some time, it falls under the busybox prompt. (I had no problem with ubuntu 6.04)
There may be an interesting detail : I've got also a plextor DVDR PX-740A. (hda) (motherboard asus a7n8x-e deluxe) I managed to save some logs (dmesg, casper.log and /proc/ide/hda/*). It may be useful. Each time I did a cat /proc/ide/hda/capacity, I got some "hda: drive not ready for command" and a capacity of 25888529. (it is strange that the copy of this file gave me 75043832). Another strange thing: the 1st time I did cat /proc/ide/hda/identify, there was only zeros, (and the hda not ready for command). the other times I got something else (but always the hda not ready for command). And finally, the DVD doesn't respond anymore, even after a reboot. I had to switch off the computer in order to make it work again. I hope this can help solving the problem. ** Attachment added: "dmesg, casper.log and /proc/ide/*" http://launchpadlibrarian.net/12473638/kubuntu_logs.zip -- Hardy alpha 2 - 5 won't boot https://bugs.launchpad.net/bugs/179336 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
