Subject: [NET][TG3] Fwd: page allocation failure with linux 3.1.1

Hello, David, Jarek and Eric!

In September 2010 I had trouble with the Broadcom Tygon 3 network driver:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=64289c8e6851bca0e589e064c9a5c9fbd6ae5dd4

Please, see below my most recent findings, where again tg3 is present.

I sent this earlier today to linux-kernel list. Sorry if this is not
related to the above, thus to the tg3 kernel driver.

Hello, folks!

Please, cc me, as I'm not subsribed to the list.

With Linux 3.1.1 I'm hitting a page allocation failure on a machine
with 512 MB RAM and 2 GB swap, which looks like this:

/dev/md/2                               partition       2007996 46912   -1

Should I try running Linux 3.1.2 or 3.1.3 ?

I'm attaching the full dmesg, as well as the kernel .config file used.

Also, if anyone needs more details about my setup - just ask, and I'll
help with what I can.

Thanks in advance,
Plamen Petrov
