Bug Description

This is a regression from Lucid, I believe. Also, opening this per a discussion with JFo at UDS.

So, I have a Lenovo S10 netbook with a Broadcom BCM4312 wi-fi card. To use this card, I have to use the Broadcom B43 driver (b43.ko) and it does not do well after a suspend/resume cycle.

Steps to reproduce:

Maverick on a system w/ B43 based wi-fi
boot, connect to AP
Suspend system
Resume system
wireless no longer connects to APs found on scan, lots of error messages in /var/log/syslog

I've tried just bouncing the B43 driver as a workaround, but that doesn't work either. I have to fully reboot after each suspend to get wireless working again.

I'll try the STA driver shortly to see if that fares any better.

The error messages seen in syslog are like the following:

Oct 25 12:01:52 AsukaLangleySoryu kernel: [ 3810.628215] b43-phy1 ERROR: MAC suspend failed

This happens after each suspend/resume cycle and requires a reboot to fix, as mentioned earlier.

Update: I've removed the B43 driver and installed the Broadcom STA driver. Thus far, It's survived one suspend/resume cycle which is doing better than B43 was for me. I'll see what happens tomorrow during a full day of suspend/resuming at UDS and see if this is a better fit.

Jeff Lane, thank you for reporting this and helping make Ubuntu better. Maverick reached EOL on April 10, 2012.
Please see this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases

We were wondering if this is still an issue in a supported release? If so, can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command in a supported release from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux <replace-with-bug-number>

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.

Please let us know your results. Thanks in advance.
