Ubuntu won't boot if a USB disk (any USB mass storage device) was plugged in before boot.

[Alpyre]

Ubuntu doesn't boot successfully if a USB disk (any USB mass storage device) was plugged in before boot.

Sytem gets stuck while booting (from LiveCD or HDInstall):
It halts with this text on the screen:

Ubuntu 9.10 username-desktop tty1
username-desktop login:

and the screen blinks together with the HD Led.

I'm facing the same issue. I have installed ubuntu 9.10 on my external HDD (Western Digital 2.5" 120Gb - Transcend SATA enclosure). It's not possible to unplug the enclosure since I have my ubuntu installation on the external HDD. I need to try booting 3,4 times to get ubuntu started. It get stuck just before the login window.

Following details may support solving this defect,

Machine Configuration;

Dell Inspiron E1505
Core 2 Duo 2.0Ghz processor
2 Gb Memory
WD 500Gb internal hdd (Windows 7)
GeForce Geo 7300 256Mb

Plugged in devices;
Transcend SATA enclosure with WD 2.5" 120Gb hdd (* this is the HDD my ubuntu 9.10 installed)
Huawei E220 HSDPA usb

Chamila.

Hi Alpyre,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 484027

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

Hi Jeremy,

This is not an issue for me since the 2.6.31-16 kernel upgrade...

Thanks...
