Ubuntu boot fails with message: phy0 - rt2800pci_mcu_status: Error - MCU request failed, no response from hardware

Hi Ulisses,

Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/daily/current/ . If the issue remains, please 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 697063

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.

confirmed in 11.04

I can't even boot to recovery to install the latest wireless driver

Everything worked in 10.10, and I can boot to the live usb of ubuntu 11.04, although the installer hangs after the first step

I had to install 10.10, boot to it, and then upgrade to 11.04 to even get to this point, but now boot hangs everytime

I have the same problem in 11.04 and can't even boot to recovery.

This is the wireless driver, you can disable it to at least get the machine to boot by pressing 'e' on the grub boot screen and editing the boot commands...

Find the 'linux' command, it should look something like this:
linux /boot/vmlinuz-2.6.32-24-generic root=UUID=c5b47225-1a42-4dd0-991c-0d883040689d ro quiet splash

There may be some other parameters in there, add the following:
rt2800pci.blacklist=yes

put it after the 'ro'

This disables the driver and allows your machine to boot.

MCU request failed.. *32bit* kernel, no firmware load issue
Ubuntu 11.04

This issue occur in my HASEE netbook (CPU: atom 450 32bits) with NetCard Ralink RT3090, when i upgrade ubuntu from 11.10 to 12.04 Alpha 2.
