I think this is related to the activity hdd. When I was actively reading data
from disk crashes frequently.
Sorry for bad english.

Using Ubuntu 11.04, I had the very same problem with my Thinkpad X120e.
Everytime I turned on the Thinkpad's WiFi adapter (a Realtek RTL8188CE in my
case) the system randomly froze.

I can confirm that installing the driver from Keng-Tu's PPA fixed the
problem with random crashing.
Im not sure if this is related but after installing the driver, I also
haven't experienced the black screen
FYI, I've filed a ticket about the freezes when resuming, this time I
was lucky enough to get it resurrected after 2 minutes.

There is a stark contrast between using the x120e with the wireless on
and off. When the wireless is enabled, even if my primary network
traffic is over the wired Ethernet adapter, the device will freeze.
With the wireless disabled, the machine can go all day without a freeze.

with hwe-wireless driver I haven't get freezes, but I have the same
problem of intermitently loosing wired and wireless connectivetity (I
ping -W1 x120e continiuosly from another computer) unless I disable the
wifi... smells like some sort of power saving feature.

@William Yes! This is exactly my experience as well.
This past weekend I spent several hours programming with wireless
disabled. The system was solid, no crashes. I enabled wireless to push
some commits, it froze while connecting to the network.

I installed Elementary OS which is base of 10.10 ubuntu

The Drivers i installed to get the wireless working is Keng-Tu's hew-wireless

Please note that there are multiple different crash bugs, not all of
them are going to be related to the wireless driver. I know of at least
one fix for crashes that has gone into the fglrx driver (if you are
running the proprietary ati driver) and some fixes to the fusion radeon
driver that went
@John, I agree. It seems as though the waking up from sleep crashes are
different from what this bug is addressing.
@Jorge, that actually makes a lot of sense with regards to signal/noise
ratios causing the crashes. I generally get them only when either there
are a lot of wifi users or when I am
@Ben Lafreniere: You may be on to something.
My crashes are only once a day or every other day and it usually, but
not always, happens on resume. May be coincidence but iirc, the last two
times happened when I suspended at work and resumed at home (both g
infrastructure networks). Also, home has
@Jorge
I do think that network size/noise must be a big factor. That would
explain those of us who don't or rarely experience crashes at home but
do on our schools' networks.

@Ryan Porter: I tried compiling the driver from source using
checkinstall rather than make install and received an error that the
driver conflicted with the kernel module for the wireless card. This may
be the reason you were experiencing crashes on startup. I wish I knew
how to resolve the issue,
We had this problem with X120e's at UDS. rtg think this is multiplied by
wireless noise, so the busier a network is the greater chance of
triggering it with RTL8192CE.
- I tried both the Oneiric kernel and the mainline kernel and it still
crashes regularly.

I'm also still getting crashes after installing rtl8192ce-
dkms_2.6.0005.1116.2010-1ubuntu1~maverick2 from Keng-Tu's PPA. Running
11.04 on an x120e.
The computer will just freeze while I am using it. It will continue to
display the screen as it was when the crash occurred, but the computer

My X120E still hasn't crashed since installing
rtl8192ce-dkms_2.6.0005.1116.2010-1ubuntu1~maverick2.
Perhaps this has something to do with first trying to install the driver from
source:
i installed Keng-Tu's hew-wireless PPA
2.6.0005.1116.2010-1ubuntu1~maverick2 and i notice less crashes but i
notice i experience crashes in my school's network and sometimes when
waking up from sleep it just becomes a black screen and nothing is

I'm running 11.04 on an X120E. It seemed like the wireless driver was
causing random crashes (I'm using a wireless N home network). I tried
installing the driver from the realtek website. This caused Ubuntu to
consistently crash on startup. So I uninstalled the driver and replaced
it with the
@Robert: That might be a problem as well, but all of the issues I've had
have been with infrastructure networks.

Could it be that our wireless causes a kernel panic when using ad-hoc
networks? I noticed someone was having similar issues with their x100e,
arch and the realtek drivers.

Seems like if it's not g vs n then there's gotta be something with big
networks that's causing the issue that isn't present with a smaller one.

I'm getting the same issues as Jason. Kubuntu seems to kernel panic
while I use my school's wireless N, but it doesn't crash on my home
network which used wireless g.

@Jason Wm. Doll: I disagree. I've never even used my network card on a
wireless-n network and it crashed all the time. Maybe wireless-n is even
worse, though.

I believe the issue is related to how the rtl8192ce driver handles
wireless n. I haven't experienced the freezes on my home b/g router but
have them too frequently to practically use wifi on my school's n
network.
