#10154: wifi device frequently disappears after lid-suspend
--------------------+-------------------------------------------------------
Reporter: dsd | Owner: dsaxena
Type: defect | Status: new
Priority: normal | Milestone: Not Triaged
Component: kernel | Version: not specified
Keywords: | Next_action: never set
Verified: 0 | Deployment_affected:
Blockedby: | Blocking:
--------------------+-------------------------------------------------------
Reproduced on 2 XO-1.5 production units in Argentina, running kernel
2.6.31_xo1.5-20100504.0041.1.olpc.346083e (sw build very similar to
10.1.1/os202).
A few cycles of close-lid open-lid will cause the wifi device to disappear
with very little of interest in dmesg.
Usually happens within 10 close-open cycles.
dmesg from one session: http://dev.laptop.org/~dsd/20100507/wifi-
disappeared.txt (scroll to the very end of the file to see the S/R cycle
in question)
Sometimes the wifi device will reappear after 1 or 2 idle-suspends
afterwards, sometimes not.
