*** This bug is a security vulnerability ***
Public security bug reported:
Binary package hint: linux-image-2.6.24-21-generic
I am using Xubuntu 8.04.1 (upgraded automatically from 8.04) on amd64, using
Amd X2 3600+, 2GB Ram and 2 Seagate Hdd`s in software Raid.
I am also using Sagem 800 E3 modem for ADSL and ueagle-atm driver.
This is the way I am getting on the internet:
~$ cat /usr/bin/eagleup
#!/bin/sh
modprobe ueagle-atm
modprobe br2684
br2684ctl -b -c 0 -a 8.35
ifconfig nas0 up
pon dsl-provider
After installing latest updates few days ago (2.6.24-21) I experieced noumerous
problems,
including: Slower work, Adsl ppp connection behaving crazy (web pages do not
open fully
and opening is VERY slow and unpredictable).
Internet radio playing begins and then Stops after a minute.
Also, Every download is slower by at least 40 percent and it stops randomly
during download
so it is completely unpredictable..
As the "cherry on top" when I shut down network interface of adsl, then all
programs locks up
stop responding, i cannot log out because buttons t\does not respond and after
killing X
with Ctrl+Alt+Backspace trying to shut down, system won`t go down even if I
press Ctrl+Alt+Del..
After selecting previous kernel: 2.6.24-19 in GRUB, everything behaves
nicely..
Internet is now Very fast like before, no freezing and everything is like it
was before.
So, my conclusion is that there is something wrong with current 2.6.24-21 in
8.04.1 for amd64.
Steps to reproduce: Just update Ubuntu amd64 to latest kernel and watch your
adsl performance and lockups.
Desired behavior: Network tranfers should not be interrupted and programs
should not freeeze, like with 2.6.24-19
Workaround: Use 2.6.24-19 kernel until problem is solved.
