2.6.24 Page Allocation Failure
From: AndrewL733
Date: Thu Jan 31 2008 - 10:55:34 EST
My setup is Mandriva 2007 64-bit:
IntelS5000PSLSATA motherboard
Single Dual Core 3 Ghz Xeon
2 GB ECC RAM
Myricom 10 GbE Network Adapter (using out of kernel 1.4.0 driver
compiled with "MYRI10GE_ALLOC_ORDER=2")
I have two identical systems doing data transfer via Myricom cards
connected directly to one another (in other words, not going through a
switch).
No problems hammering Myricom with 350 MB/sec NFS traffic while running
2.6.20.15 and 2.6.22.9 (kernel.org "plain vanilla" kernels I compiled
and run, also with updated Myricom drivers). However, I just compiled
and installed 2.6.24 and get the following errors as soon as I begin
doing NFS I/O over the Myricom card. Maybe I missed something in the
kernel configuration? Throughput when running 2.6.24 is about 40 percent
lower than when running 2.6.22.9-- surely due to these errors.
