Suspend/hibernate loses access to wireless access points

[humdinger70]

[EXPLANATION AND WORKAROUND]
With ubuntu 10.10 some hardware that was previously driven by the rt2860sta driver is now driven by default by the rt2800pci driver. Sometimes the new rt2800pci does not work as well as the rt2860sta. In that case it is often possible to switch back by blacklisting. See how to switch between the drivers here: https://answers.launchpad.net/ubuntu/+question/132350

[ORIGINAL REPORT]
Under Ubuntu 10.10 UNE, If I suspend or hibernate, coming back from either, system can't locate any wireless access point - even if I'm actually sitting right next to it. Have to reboot for any to be discovered. I always make sure to disconnect first before doing suspend/hibernate.

I do have a swap partition, 3GB in size (1.5 times my system RAM). Suspend and hibernate do function correctly.

Hardware is ASUS EEE PC 1000, 2GB RAM, 40GB SSD. Note: this never happened with EasyPeasy 1.6/Ubuntu 10.04 on same box.

Hello
Is this problem present with the latest updated Lucid's or Maverick's packages?
Thanks in advance
Fabio

[humdinger70 (lgreenwa)]

It's with Maverick (10.10).

Hello
due to:
Nov 1 16:26:37 larry-laptop kernel: [ 0.008000] Atom PSE erratum detected, BIOS microcode update recommended
Can you verify if your bios version is updated ?
Thanks
Fabio

[humdinger70 (lgreenwa)]

Fabio, I've had issues in trying to upgrade the BIOS. Several times in trying to update it has caused it to boot only to a black screen. I wound up just using the existing BIOS because it works.

Thank you for taking the time to report this bug and helping to make Ubuntu better. This particular bug has already been reported and is a duplicate of bug 594866, so it is being marked as such. Please look at the other bug report to see if there is any missing information that you can provide, or to see if there is a workaround for the bug. Additionally, any further discussion regarding the bug should occur in the other report. Feel free to continue to report any other bugs you may find.

[Wolfgang Kufner (wolfgangkufner)]

It is not a duplicate of bug 594866, because here (bug 664735) there is no "rt2800pci_load_firmware: Error - PBF system register not ready."
The rt2800pci here actually loads the firmware and connects.
This here being a 32 bit system makes the difference.

[Wolfgang Kufner (wolfgangkufner)]

Lspci.txt tells us:
Kernel driver in use: rt2800pci
 Kernel modules: rt2860sta, rt2800pci

Your system used the rt2860sta on lucid. With maverick rt2800pci became the default driver.

There are two things that can be done now:
a) try to fix the resume issue with the new (rt2800pci) driver
and/or
b) switch back to the rt2860sta (it is a different version from lucid, however) by blacklisting the rt2800pci. Find out how e.g. in the not really a duplicate bug 594866.

[Wolfgang Kufner (wolfgangkufner)]

@humdinger70

I have placed a possible workaround in the bug description at the top.

It would be nice if you could try the "install rt2860sta /bin/false" thing that is explained in the link I put there. Maybe the rt2860sta simply interferes with the rt2800pci after wakeup. I think it is worth a shot.

If not then hopefully the rt2860sta works for you.

[Wolfgang Kufner (wolfgangkufner)]

Do you still have this bug?

Some possible causes to investigate would be pcie_aspm or even (very long shot) rfkill interfering or an ASUS EEE PC 1000 platform driver.
