Today I updated several servers running CentOS 4.3, and got the new 2.6.9-42 kernel. One of the machines serves as our firewall. After rebooting I lost all forwarding thru the machine. I reverted back to the 2.6.9-34 kernel and connectivity returned. During the few minutes that the new kernel was running I checked that the routing table looked OK, and with tcpdump I saw that indeed no traffic

Hi, another issue I''m seeing with 3.0-rc2 and Xen is that there is an unexpectedly high amount of kernel reserved memory. I suspect that Linux allocates page table entries and corresponding data structures for the whole 6GB areas of the provided ''physical RAM map'' even though it has rather big unusable holes in it.
