Subject: 2.6.39.2: page allocation failure question (__alloc_pages_nodemask+0x626/0x860)
Date: Sun, 26 Jun 2011 19:04:34 -0400 (EDT) [thread overview]
Message-ID: <alpine.DEB.2.02.1106261902050.9133@p34.internal.lan> (raw)
Hi,
[41624.229468] irq/52-eth0: page allocation failure. order:1, mode:0x20
[41624.229472] Pid: 1980, comm: irq/52-eth0 Not tainted 2.6.39.2 #1

I do have enough swap available:
Mem: 16434572k total, 16165796k used, 268776k free, 9068k buffers
Swap: 31246388k total, 18296k used, 31228092k free, 11210636k cached
Perhaps I am just noticing this due to using the threadirq boot option
but is it normal to have page allocation failures on kernel processes if
physical memory use is high/full and swap is available?
Justin.
