[intrepid] fail to connect after resume with rt73usb

[Id2ndR]

On Intreprid alpha 5, when resuming from STR, wlan0 interface doesn't work :
- NM doesn't see wireless networks and stay disconnected
- it's impossible to do "iwlist wlan0 scan" and "ifconfig wlan0 up"

To correct this, just remove rt73usb module and reload it (removing rt2x00 related modules isn't needed) : $ sudo rmmod rt73usb && sudo modprobe rt73usb

Hi Id2ndR,

Care to attach your dmesg output after a Suspend/Resume cycle? Also, just curious if you possibly test Alpha4 and if this issue existed there as well? The reason I ask is because Alpha4 contained a 2.6.26 kernel and Alpha5 contains a 2.6.27 kernel and we're hoping to note and specific regressions. Thanks.

[Id2ndR (id2ndr)]

I just tested with Alpha3, shiped with linux 2.6.26-4. I have some SQUASHFS errors but they don't affect the networking part.

Time :
279 : I put the rt73 based wifi dongle
=> wifi is OK (available networks listed in NM)
380 : going to sleep
400 : finish to resume (the cd burner taked a long time to read the live CD)
=> running "sudo iwlist wlan1 scan" return "network is down" (wlan0 was intel wifi and modules were removed).
449 : removing rt73usb
455 : reinserting rt73usb
=> wifi is OK

[Id2ndR (id2ndr)]

More information :
- I run tests with alpha3 on my laptop because my desktop computer don't resume on liveCD without nvidia proprietary driver (that's why there is an wlan1 on my laptop, but not on my desktop running alpha5).
- resuming is OK on 2.6.24 (on my laptop running hardy, up to date).

So the regression appeared between 2.6.24 and 2.6.26-4.

Marking it as confirme since tests have been done.

It doesn't work either after a suspend to disk.

[Id2ndR (id2ndr)]

It seems that now (linux 2.6.27-4) it prevents the computer from resuming (from RAM and from disk). In fact the screen displays a blinking dash and the computer is unresponsive.

In my box, removing rt73usb prior to suspending makes it possible do wake up.
Upon waking, modprobing it back makes it possible to connect normally.

a-ha! im having this problem too. except that this problem only occurs 50% of the time. and when it does occur, i have a problem turning off my computer; the usplash bar empties completely, but then it hangs and doesnt turn off unless i press and hold the power button.

the other 50% of the time, everything is fine and i wake from suspend without any other problems.

i am using intrepid final with latest updates applied.

I have the same problem with Zonet ZEW2500P (ralink rt2501) and Intrepid using 2.6.27-9-generic.

[Id2ndR (id2ndr)]

You may look at bug 274734 and try to use the attachement I made for zd1211 module. You only need to change the name of the module in the script.

This bug was reported in the Intrepid development cycle; removing regression-potential and marking as regression-release.

Per a decision made by the Ubuntu Kernel Team, bugs will longer be assigned to the ubuntu-kernel-team in Launchpad as part of the bug triage process. The ubuntu-kernel-team is being unassigned from this bug report. Refer to https://wiki.ubuntu.com/KernelTeamBugPolicies for more information. Thanks.

Hi Guys,

Just curious if anyone who had this issue was able to test the latest Jaunty 9.04 release yet and confirm if this issue remains? Please let us know. Thanks.

[zippidy_josh (redstone)]

Yes, this issue still remains on Jaunty 9.04.

The bug doesn't exist anymore in linux 2.6.30rc5 (same behavior that bug 350941, so I think this bug is a duplicate because it seems to share the same mac80211 and cfg80211 modules that may have been the origin of the trouble).

[zippidy_josh (redstone)]

Cool. Out of curiosity, do you happen to know what was the root cause of
the bug, or the CL that fixed it?

No I haven't got more information. Someone may test several linux version from the PPA to detect the exact version that first fixed the bug and then check for the changes.

[Leann Ogasawara (leannogasawara)]

Based on the following comment from Id2ndR the original bug reporter, it seems this should now be resolved with the latest Karmic release. Updating the status from Fix Committed to Fix Released for now. Thanks.

[zippidy_josh (redstone)]

Yup, Karmic works for me. Thanks
