Okay. I'm in Seattle now. Yes, it solved the issue, but surely an #if 0 isn't a proper solution. What's the actual bug here? I'm afraid the meaning of what's going on here isn't exactly intuitive. Also, I'm doing an 8 hour run with this patch tonight. Maybe more, depends on when I wake up. ;) I think if this resolves the issue on two separate ≈8 hour runs, it should be considered the solution to the issue, unless it resurfaces. - Steven _______________________________________________ ath9k-devel mailing list [email protected] https://lists.ath9k.org/mailman/listinfo/ath9k-devel
