Bug#571465: linux-image-2.6.32-2-amd64: Kernel WARNING from wdev_cleanup_work when hibernating
Package: linux-2.6
Version: 2.6.32-8
Severity: normal
My laptop hibernated due to low battery last night, and this morning after
un-hibernating it I noticed the signs of an oops mentioned in my terminal
window. Digging through the kernel log, I found these, one during hibernate
and the other during un-hibernate:

As always, I'd consider the subsequent oops suspect due to the previous
WARNING.
Digging through the source turned up:
static void wdev_cleanup_work(struct work_struct *work)
{
struct wireless_dev *wdev;
struct cfg80211_registered_device *rdev;
wdev = container_of(work, struct wireless_dev, cleanup_work);
rdev = wiphy_to_dev(wdev->wiphy);
cfg80211_lock_rdev(rdev);
if (WARN_ON(rdev->scan_req && rdev->scan_req->dev == wdev->netdev)) {
rdev->scan_req->aborted = true;
___cfg80211_scan_done(rdev, true);
}
cfg80211_unlock_rdev(rdev);
mutex_lock(&rdev->devlist_mtx);
rdev->opencount--;
mutex_unlock(&rdev->devlist_mtx);
wake_up(&rdev->dev_wait);
dev_put(wdev->netdev);
}
That WARN_ON corresponds to the line given for the initial WARNING.
