Summary: Intermittent TCP issues with => 2.6.27
Product: Networking
Version: 2.5
KernelVersion: 2.6.27
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: IPV4
AssignedTo: shemminger@linux-foundation.org
ReportedBy: speedster@haveacry.com
Latest working kernel version: 2.6.26.8
Earliest failing kernel version: 2.6.27
Distribution: Ubuntu
Hardware Environment: amd64, KVM
Software Environment:
Problem Description:
As reported in LP #296767
(https://bugs.launchpad.net/ubuntu/+source/linux/+bug/296767) I am experiencing
intermittent TCP issues over a PPP ADSL2+ connection with the only change being
an upgrade to 2.6.27.
A number of websites, ping, traceroute work correctly but I simply can't
connect to several including:
- store.apple.com
- youtube.com
- ANZ internet banking (anz.com.au)
- MSN messenger
I have also tried compiling a generic 2.6.28-rc4 kernel and this still suffers
from the same issue, however if I reboot into the previous Ubuntu kernel
(2.6.24) or a vanilla 2.6.26 kernel the issue disappears.
Steps to reproduce:
1. Use a KVM guest as a gateway to a PPP internet connection
2. Boot with kernel <= 2.6.26
3. Observe functioning networking
4. Boot into 2.6.27+
5. Observe broken networking
