Hello,

 

Does any one else have the same problem or solution for it?

A newly installed opensuse 10.3, vmware, open-iscsi (2.0.866-15) combination
keeps crashing. It might have something to do with the network drivers as I
see "hw csum failure" in the messages log file.

Sometimes the open-iscsi hangs leaving iscsi-mount inaccessible, sometimes
the whole machine freezes. The problem occurs when doing extensive
read-write, it is possible to read-write non-extensively before the crash.

 

Kernel: Linux version 2.6.22.17-0.1-default ([EMAIL PROTECTED]) (gcc version
4.2.1 (SUSE Linux)) #1 SMP 2008/02/10 20:01:04 UTC

 

My messages file looks like this when open-iscsi hangs:

Any ideas?
