[Bug 384039] Re: Check for hardware regression before upgrade

[Phillip Susi]

A blueprint or the mailing list is the place to discuss such an idea.
It also isn't really relevant to ubiquity; the update-manager would be
the place to do this.

Title:
  Check for hardware regression before upgrade

Status in “ubiquity” package in Ubuntu:
  Invalid

Bug description:
  Binary package hint: ubiquity

  There should be a verification for critical hardware regression before
  performing an upgrade.

  That should be implemented at two levels.

  1. The live-CD should check when launching the Ubiquity
  2. The upgrade manager should also check it when it upgrade to a new version.

  In case of incompatibility due to a regression, the user should be
  invited to install a previous version, or not to perform the upgrade.

  I think that the verification could be very fast : there are not 1000
  open critical bugs due to regressions. One just need to compare the
  result of lspci with a blacklist of hardwares that are impacted by
  critical regressions. Each of these have to be associated with the
  name of the last working version of Ubuntu.

  For example, due to bug  359392[1], if someone has the Intel chipset
  GM965/GL960, he has to be invited to install (or remain on) Intrepid
  before installing (or upgrading to) Jaunty.
