Bug Description
Re-installing Precise with kernels 3.2.0-26 or 3.2.0-27 from the precise-updates repo hangs forever when searching for install media on systems that do this from check-missing-
When the installer detects that it needs to load some missing firmware, it tries to mount every available partition as '/media'. If the hard drive is already partitioned and has an extended partition, the installer will try to mount the extended partition and hang indefinitely. Sending SIGKILL to the mount command does nothing.
Eventually, the kernel will start logging 'INFO: task mount:3559 blocked for more than 120 seconds.' messages.
To reproduce, on ThinkPad T420s (or most other laptops with wireless) that already has Ubuntu installed with an extended partition (for example, sda2):
1. Boot the kernel/initramfs for the network installer at /ubuntu/
2. Select language and keyboard options
3. Installer hangs forever
4. Alt-F2 to another terminal
5. Run ps, see stalled mount command, like 'mount -tauto /dev/sda2 /media'
On 3.2.0-23, the mount command will return immediately with an error, as expected (since mounting and extended partition doesn't make sense).
Regardless of what hardware is used, running the mount command on an extended partition always stalls. The hardware only makes a difference in deciding whether the mount command is called during install.
