Description VDR dai (bugzilla) 2007-10-11 10:40:55 UTC 
Most recent kernel where this bug did not occur: 2.6.21
Distribution: Debian GNU/Linux (unstable)
Hardware Environment: MSI 875P Neo (Intel Corporation 82547EI Gigabit Ethernet Controller)
Software Environment: uswsusp 0.7-1 
Problem Description:

If I do s2disk, hibernate is fine.
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.

The output of lspci -vv before suspend and after resuming are same.

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!
