The HTB classify hash has a scalability issue in kernels below 2.6.26.
Patrick McHardy fixes that up in 2.6.26.  What kernel version are you
using?
I'm using 2.6.26, so I guess the fix is already there :(
If Jesper meant the change of hash I can see it in 2.6.27 yet.
I'm referring to:

 commit f4c1f3e0c59be0e6566d9c00b1d8b204ffb861a2
 Author: Patrick McHardy [off-list ref]
 Date:   Sat Jul 5 23:22:35 2008 -0700

    net-sched: sch_htb: use dynamic class hash helpers

Is there any easy git way to figure out which release this commit got
into?
I guess git-describe, but I prefer clicking at the "raw" (X-Git-Tag):
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff_plain;h=f4c1f3e0c59be0e6566d9c00b1d8b204ffb861a2
I think I prefer the command line edition "git-describe".  But it seems 
that the two approaches gives a different results.
(Cc'ing the git mailing list as they might know the reason)

  git-describe f4c1f3e0c59be0e6566d9c00b1d8b204ffb861a2
  returns "v2.6.26-rc8-1107-gf4c1f3e"

  While you URL returns: "X-Git-Tag: v2.6.27-rc1~964^2~219"

I also did a:
"git log v2.6.26..v2.6.27 | grep f4c1f3e0c59be0e6566d9c00b1d8b204ffb861a2"
commit f4c1f3e0c59be0e6566d9c00b1d8b204ffb861a2

To Radu: The change I talked about is in 2.6.27, so you should try that 
kernel on you system.
