Status: RESOLVED WORKSFORME

(Firefox OS Graveyard :: GonkIntegration, defect)

Description

[Jonathan Griffin (:jgriffin)]

Booting B2G on the panda often fails with the message:

I/wpa_supplicant( 1398): wpa_driver_nl80211_driver_cmd: Unsupported command SCAN-ACTIVE

As soon as this appears in logcat, the panda reboots itself.  It will repeat this cycle for somewhere from 1 to 10 times before finally coming up correctly.

Normally, the unsupported command should not be a problem. I also see it in logcat.

We just reverted some kernel and libc changes. Could you try again and see if anything has changed?

Comment 2

[Jonathan Griffin (:jgriffin)]

I am still seeing nearly the same behavior, except that I no longer see 

I/wpa_supplicant( 1398): wpa_driver_nl80211_driver_cmd: Unsupported command SCAN-ACTIVE

in logcat; the last line is now:

D/wpa_supplicant( 1398): nl80211: Scan trigger

In the serial output, I see these errors (from three different instances) right before the panda restarts itself:

I also see this error when it finally boots correctly.

Comment 4

[Thomas Zimmermann [:tzimmermann] [:tdz]]

All these errors are not much of a problem. I see them as well. In fact, they are even in the kernels that come from upstream.

Comment 5

[Jonathan Griffin (:jgriffin)]

Seems to have been fixed since bug 817730 was addressed.
