I'm another user of a mini 311c on ubuntu 13.04.
I have added pcie_aspm=force to my boot options, and I can suspend, but once
only !!
What can I do to help fixing this bug ?

I strongly advise you to replace the module. I replaced it with
WiFi/Bluetooth (use partnumber 575920-001 for queries), and never had
another issue.

I tried replacing the wifi/bluetooth mini pci-e card with one from ebay culled
from a Dell laptop (BCM94312HMG) - the HP stopped with a BIOS error message on
rebooting :(
I've ordered a 575920-001 so I'm looking forward to standby/hibernation heaven
from now on. Cheers Sam.

Yes they check it in bios, you can only use hp approved parts. There is
a hack but seen the price, just get one that works is easier...

Following the advice in post #2, sudo ifconfig wlan0 down in virtual
terminal 1 instantly locks the computer. Nothing results from doing the
advice in post #6, and looking at kern.log post-reboot reveals no log
entries relating to the attempt to shut the interface down.
HP 311c running 12.04
Just tried a fresh xubuntu 12.04 install on my compaq 311c to no avail..
I also tried to enable the network adapter boot device in the bios,
which some how changed the behaviour. As of now halting and reboot works
but not suspend.
Is any body loking at the bug? Is there something we can do?
Updated my HP 311c laptop to 12.04; suspend either hard-locks the
machine or 'bounces' back into screensaver password. Trying to shut the
machine down results in hard-lockups probably 70% of the time. I've
installed compat-wireless from the repositories which improved matters a
little (100% lockup
Hi,
Sorry to have to come back to this...
The solution given above works only in 11.04, I'm running 11.10 and the
backport version is linux-backports-modules-cw-3.2-oneiric-generic, which
doesn't solve the issue.
Right now I'm runnning my laptop with ath9k blacklisted, and modprobe it

I'm running 11.04 ubuntu on a HP 311c laptop; suspend and hibernate did

Hi guys
In the end I replaced the module by a Broadcom one a few weeks ago. The
laptop is running as clean as can be. It never freezes, I suspend/resume it
all the time and I disable/enable network at will. I rebooted maybe 2-3
times over the past weeks, mainly because of installed updates.

Hi,
I am also affected by this bug on a Compaq Mini 311C with Xubuntu 11.10
(3.0.0-12-generic kernel).
lspci gives:

A simple sudo rmmod ath9k suffices to freeze the system completely
If the first device in the boot order is not an adapter (ath9k) - system

ath9k
Is anyone able to try the steps in comment #6 to see if more information
can be collected to help in debugging the issue? Right now there's very
little information to go on, and since many machines use ath9k without
this issue it's difficult to know what's special about the
configurations affected
Well this is worse in 11.10. Even proactively unloading the modules make
the laptop freeze. With the 6 month release cycle this issue remains in
place for at least 1,5 years now, which is a lot... I guess I need to
replace the module by an Intel based model to be in the green.

i can confirm this bug.. 11.04 is unusable because of it. i need to boot
with 2.6.35-30 (the kernel from 10.10) as no other kernel i've tried is
able to get past the point after i enter my login info,and press enter.
shortly after the background changes (as part of the login process) but
before
my machine is an acer aspire one 522-bz623

@Sam: Here's something else to try. Induce the lockup from virtual
terminal 1 and then press Alt-Sysrq-9 then Alt-Sysrq-P. If that produces
some output, please take a photograph or something to capture the
output. After that you can also try pressing Alt-Sysrq-L and Alt-
Sysrq-T, then wait a few
@Sam, please try the following. Switch to virtual terminal 1 (press
Ctrl-Alt-F1) and log in. Run ifconfig and identify the interface that
represents your wireless device (e.g. eth1), and then run 'sudo ifconfig
eth1 down' (using the interface for your wireless). Please let me know
if the system
Hi,
Bringing the interface down was no issue, but bringing it back up (sudo
ifconfig eth1 up in the analogy) gave an instant freeze. Needed to hard
power down the system and reboot. Everything working fine after reboot.
Nothing shows up in the console at all.
I just noticed with 11.04 I don't
@Sam, you can look in /var/log/syslog and /var/log/kern.log. You may
find something there, but if it's really locked hard then there probably
won't be anything useful logged there. It's worth checking though.

Hi,
No luck... I can see the ifdown in the logs, but followed by the system
boot. I left 10 seconds between ifdown and ifup to get clear time stamps. No
ifup in the logs...
And I've had the issue on ifdown as well. So it's the state change in both
directions that triggers it.
