Re: [Xen-users] xen kernel errors
Still having the problem.
Concerning igb error I have tried the following one at a time:
New igb driver from Intel site.
kernel parameter pcie_aspm=off
ethtool -K eth0 tx off on dom0
ethtool -K eth0 gro off on dom0
Concerning the enlighten.c error. While it does seem to do anything if it
concerns me power management may be it's the real cause of problems.
I got the debian kernel source and line 726 is the line with the *****
static void xen_clts(void)
{
struct multicall_space mcs; *****
mcs = xen_mc_entry(0);
MULTI_fpu_taskswitch(mcs.mc, 0);
xen_mc_issue(PARAVIRT_LAZY_CPU);
}
Means nothing to me :-(
It has never died doing iperf from dom0 or domu <> external.
Never died during network backup.
Usually takes a least a few hours and has never made it a day running a domu.
Any ideas?
I'm pretty much down to different network cards.
