Bug Description

When attempting to either manually partition, or install using an entire disk on powerpc hardware, the install process hangs at the step of formatting the swap partition. I can still switch between VTs etc.

Attached are the syslog and partman log to help identify the issue. The syslog is augmented with DEBCONF_DEBUG=developer, as well as -x being used in /lib/partman/commit.d/30parted and /lib/partman/commit.d/45format_swap.

Sorry, I should clarify that this is with the alternate installer.

I also get the same behavior with ubiquity on the desktop CD.

Moving to parted, as things go pair shaped when ped_timer_new is called from within timered_file_system_create. ped_timer_new is a libparted function, and as shown by the strace, time(NULL) is the same number twice, before the timer_handler callback is called with information from the libparted timer functions.

I have now discovered that gparted also fails to create/format a swap partition on a mac partition table. In addition, I have managed to reproduce this using an external drive on both powerpc and x86. The only thing thats baffling, is that gparted doesn't appear to use any of libparted's timer functions, which is where parted_server was choaking for the installer. I'll get an strace of gparted to see if there is anything that may help identify the issue.

SOme developments.

Gparted on jaunty behaves the same as karmic with mac partitions, so it is hitting a different issue, not related to this bug, so gparted evidence is useless here.

After running an ubiquity install on i386, I noticed that a timer exception is also thrown, but things keep on going with no issue.. Attaching i386 logs.
