           Summary: kernel BUG at drivers/xen/netback/netback.c:349
                    (net_rx_action)!
           Product: Xen
           Version: unstable
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: critical
          Priority: P2
         Component: Hypervisor
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: pl@xxxxxxxxxx
                CC: hohnbaum@xxxxxxxxxx,niv@xxxxxxxxxx


The system is a P4 2.8 GHz, 512 MB (256 for dom0).

The network card according to lspci:
0000:04:03.0 Ethernet controller: Intel Corp. 82541GI/PI Gigabit Ethernet 
Controller

I'm using the defult config, in which it appears that both
CONFIG_XEN_NETDEV_GRANT_TX and CONFIG_XEN_NETDEV_GRANT_RX are enabled by 
default.

***
I retried the test, turning these options off for both dom0 and domU kernels,
and I did not hit this bug.

hg tip is:

summary:     Xenstore testsuite robustness: save output rather than rerun on
failure.

I have a file-backed vbd domU partition that resides on an NFS server mounted by
two machines.  I've used this for migration testing in the past.  When I just
tried to bring up the guest, I got this error while it was booting:
(XEN) (file=grant_table.c, line=1152) Bad flags (5) or dom (0). (NB. expected 
dom 0)
(XEN) gnttab_donate: gnttab_prepare_for_transfer fails
