Or quite something else. I have personally experienced a situation with a big bunch of servers where a FSC box running RHEL4U2 happily slows to a crawl when upgraded to RHEL4U3 or newer. Reason being certain MPT Fusion driver versions and Fujitsu MAW-drives with 5201/5202 firmware. Sequental read/write speeds dropped to abysmal, as did real world application performance. I tested current (at that time) Fedora kernel and experienced no problems regarding performance. After dicking around for more than a year with Redhat support, I called quits with them. No real progress was made. After RHEL5 was released and I found it working out-of-the-box with those servers, so I simply shuffled boxes around to upgrade all affected hardware to run RHEL5. However it should be noted that FSC fully supported RHEL4 U3 and upwards without regard to this. RHEL4U6 has finally fixed this problem. https://bugzilla.redhat.com/show_bug.cgi?id=194462 As another example, I run EMC MPFSi on a another bunch of servers. Their requirements list RHEL4 Update X, but all they really want is the kernel of specific version (due kernel modules shipped). So I'm running it on RHEL5U5 with U3 kernel. Yea, probably they're reading this... -- Jussi _______________________________________________ rhelv5-list mailing list [email protected] https://www.redhat.com/mailman/listinfo/rhelv5-list
