[ubuntu-uk] UEFI bios update

Hi all, just following up on this post:

"I would also suggest though that if you had no issues on Quantal but
are in Raring that it may be a kernel issue.  Just because it is
stable for everyone else doesn't mean it is for that particular
machine,  So I would file a bug first and see if there is any news
from that before you go all kung-fu on the bios/uefi system.
"ubuntu-bug linux" in a terminal will file most of the information on
a kernel bug for you."

I followed this issue up with a bug report (
https://mail.google.com/mail/u/0/?shva=1#search/bios+update/13e557738ad3f9bc),
but have hit a snag - also now detailed in the bug report.

Following the instructions from the bug report I installed the upstream
kernel to see whether that would fix the system freezes i was having.
However my ability to test that kernel is limited by the fact that i can't
get the wireless to work on the upstream kernel. I am not sure what the
problem is here as wireless works on the current kernel and all the drivers
remain installed when i boot to the upstream kernel.

During the time i spent on the upstream kernel - tethered to the internet -
i didn't have any freezes (working for about 12 hours) this is most
encouraging, but i could use more time on it to really see whether its
working. Also, the freezes on the current kernel are killing me, so if i
could find a fix, or find a way to use the upstream kernel with wireless,
that would be great.

With the help through the bug report taking a little while to happen i was
wondering if someone here might be able to help me trouble-shoot the
wireless issue on the upstream kernel. Why wouldn't it work if it works on
the current kernel and all the drivers remain installed? I don't know where
to begin.

Wireless card is: Broadcom Corporation BCM43228 802.11a/b/g/ and is
currently running using the Broadcom 802.11 Linux STA wireless driver.
Machine is running 64 bit 13.04.

I realise that this question is deviating from my original one - about UEFI
on a BIOS update - but i see this as all being part of the solution. When i
manage to get round to calling Lenovo i will follow this email up with info
about the EUFI and BIOS update.

Thanks,

j
