Re: [Xen-devel] Strange error in domU after dom0 update



A short update:

Error message in the domU:
netfront: rx->offset: 0, size: 4294967295
(comes over and over...)

The iSCSI error message is:
[ 30.649610] connection4:0: ping timeout of 5 secs expired, last rx 4294897458, last ping 4294898708, now 4294899958
[   30.649651]  connection4:0: detected conn error (1011)

Typically after a while the following stack trace appears:
