Get a Intel D940, dual core with 3 intel Pro 1000 network cards. 2. Install FC5 Xen0. 3. Upgrade with yum to kernel 2.6.18-1.2200.fc5xen0 3. Run one or more XenU guests (idle) (is this realy needed?> 4. Do a network based install over eth0 to a laptop (HTTP) Actual Results: The syslog is flooded with messages: kernel: Attempt to allocate order 5 skbuff. Increase MAX_SKBUFF_ORDER. Expected Results: ? Additional info:
I migrated the machine (and the Xen-guests) to FC6 with yum. The problem still exists with kernel 2.6.18-1.2849.fc6xen on FC6. Another way to reproduce the problem is to do a xenguest-install. This produces some nice HTTP traffic over xenbr0, which causes the symptoms in syslog.
