Hey Kim,

As I recall, I added noapic to grub2 as a workaround.  CD drives work
now, and no strange messages from dmesg.  CD drives recognize blank CDs
properly as well as burned CDs.

It's not the correct way of handling this, but it worked for me and
Tomasz Czapiewski back in May.  (I can't remember, but I think that was
10.04 lucid)

Anyhow, I edited the /etc/default/grub file to include the parameter
"noapic" towards the end of the GRUB_CMDLINE_LINUX_DEFAULT line...  

Just like it says in the file, I ran 'update-grub' afterwards, which
actually updates the grub config.

Good luck.

Kind regards,

Iestyn

Date: Wed, 01 Dec 2010 06:31:48 -0000

I have the same problem, also reported previously on different kernels ,
lucid onwards.  I am now on maverick, and same problem, though not as
frequent.  I have installed backport of 2.6.37, and getting the same
problem. uname -a => Linux pio 2.6.37-020637rc2-generic #201011160905
SMP Tue Nov 16 09:08:47 UTC 2010 x86_64 GNU/Linux

It also affects USB devices, and can sometimes cause all USB devices to fail.  I have pata_via module
I can reproduce effect by loading system, ethernet transfers, tv tuner working and running virtualbox.  At other times, it sometimes fails with practically no load on system.

Bug description:
After upgrading from Karmic to Lucid Beta 1, my CD/DVD drive stops working (it doesn't detects inserted media). When I insert a CD or DVD, the light flashes but nothing more happens.

I have the following messages on dmesg:
