Lots of "BUG eth1 code -5 qlen 0" messages in 2.6.24

Hi,

I've just started to use 2.6.24 on my home firewall (before it was
running 2.6.24-rc2 for about 65 days) and I noticed a couple of error
messages I've never seen before:

Jan 29 07:50:54 gateway kernel: BUG eth1 code -5 qlen 0
Jan 29 08:28:30 gateway kernel: BUG eth1 code -5 qlen 0
Jan 29 08:57:30 gateway kernel: BUG eth1 code -5 qlen 0

Jan 29 10:16:48 gateway kernel: BUG eth1 code -5 qlen 0

Jan 29 10:45:48 gateway kernel: BUG eth1 code -5 qlen 0

Jan 29 11:10:01 gateway kernel: BUG eth1 code -5 qlen 0
Jan 29 11:10:02 gateway last message repeated 9 times

The message seems to be coming from the qdisc_restart() in
net/sched/sch_generic.c which was changed with commit
5f1a485d5905aa641f33009019b3699076666a4c .

The NIC is an IBM EtherJet cardbus card using the xircom_cb driver:

Question is: do I need to worry about these messages or are they
harmless?
