After bisecting 2.6.39.1 it turned out that the bug is caused independently by two patches: commit b262a5da755cc6ed0cb4fba230cd9bf4037e1096 sch_sfq: fix peek() implementation and commit 9df49f2bfe862573911a080c75a6d81113c5c81d sch_sfq: avoid giving spurious NET_XMIT_CN signals Reverting these patches makes HFSC work again. From: 00bormoj@xxxxxxxxx > I had the same problem when I upgraded to 2.6.38 vanilla (and > currently at 2.6.39.1), but I can't remember what the last successful > version was (probably greater than 2.6.32). My syslog was full of the > WARN_ON trace from sch_hfsc.c:1427. Did you tested 2.6.38 or 2.6.38.8? Because mentioned patches was included in 2.6.38.8. -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
