Oneiric installer can't display anything.

Hi Tim,

Could you give this kernel a try and see if it works? (for amd64)

Marking as Incomplete, as we are waiting on Tim's reply

[Ara Pulido (ara)]

Tim, can you quickly try installing 11.04 in one of those systems, please? We would like to confirm whether this is a regression or a new issue.

Thanks,
Ara.

Thanks Tim, I think that based on that we can qualify this as a regression

Marking it back as Triaged, as Tim provided the needed information
