[Bug 1067899] Re: ubiquity fails installing lubuntu 12.10 ppc

[melchiaros]

I have read the apport-collect logs for ubiquity, but could not see any
obvious problem there. May be someone with more experience can recognize
more, but for now I would say, with respect to the trace in

WifiSyslog.txt

,that this is a kernel bug.

A quick internet search give the hint that failed paging request to

Unable to handle kernel paging request for data at address 0x0000004c

pointed(along other possibilities) to incompatible hardware.

Reading the trace shows

ieee80211

and

b43legacy

which indicates a driver problem with a broadcom wifi chip/adapter ,
which is propably integrated.

Title:
  ubiquity fails installing lubuntu 12.10 ppc

Status in “ubiquity” package in Ubuntu:
  Incomplete

Bug description:
  Putting special boot parameter:
  live video=radeonfb:1440x900-32 at 60

  (sorry i don't have the at sign on my computer because of the not
  finished installation) i succeed in getting correct screen display.
  Then, i start the installer (ubiquity) which apparantly works fine but
  then hangs on a point called 'Hardware Erkennung' (something like
  'Checking hardware' - after an installation of a basic file system).

  This happened today with the daily built 20121017 as well with a daily
  built of 3 days ago.
