When resuming, in a short time, network does not work until ifdown/ifup eth0.
No dmesg and syslog attract my attention, but network is unreachable.

Steps to reproduce:

1. boot
2. s2disk
3. press the power button

dmesg

I'm using the nvidia driver.
However, whether the nvidia module has ever been loaded
does not matter for the symptoms, it is reproducible without.

an net card driver problem?
please try 2.6.27 and see if the problem still exists.
Comment 8 VDR dai (bugzilla) 2008-11-20 03:28:38 UTC 
2.6.24 is still NG.
2.6.26 is OK.

Thanks!
