After upgrading from Fedora Core 6 (2.6.22) to Fedora Core 12 (2.6.32) I
started seeing page allocation failures when running a UDP multicast packet
writer under load. Under particularly high load, the machine sometimes crashes.
This was fixed on one machine by adding memory (total memory increased
We run 'ntpdate -q' once daily to check the ntpd sync status of the hosts in
our network. On one host, this check is failing sporadically today:
$ for i in `seq 1 10` ; do ntpdate -q 192.168.129.110 ; sleep 1 ; done
server 192.168.129.110, stratum 4, offset -0.001034, delay 0.02693

experiencing significant packet loss on an Intel 82574L NIC running on the
e1000e driver. I was not experiencing this with kernel 2.6.30. I notice 2.6.30
uses e1000e version 0.3.3.4-k4 whereas 2.6.31 uses version 1.0.2-k2.
