Public bug reported:

1st attempt installing 9.10 Karmic Koala on a Vista Home Premium laptop
(Acer 2920z), I load up Ubuntu, do a search for hardware drivers to
install. 2 entries for Broadcom appear. Installing the first (the one
that mentions Firmware something or other) causes a kernel panic, and
I'm locked out of the OS.

Can't get back into Ubuntu, even in safe mode, do a fresh install, try
installing the 2nd Broadcom driver this time, nothing happens, the
"downloading and installing" progress bar continues to move, but there's
no disk movement. Stays the same for a further 10+ minutes, I click the
Crash Report logo icon that has now appeared, and end up typing this.

Disappointed, previously used 8.1 on this laptop, and was hoping 9.1
would finally be the answer. Seems I'm back to using Vista now, until I
can have a stable and wireless enabled laptop running linux : (
