Hi, all

Just upgrade to kernel 3.2. But I find many vmalloc page errors in dmesg, such as

Code:

[   10.147072] vmalloc: allocation failure: 0 bytes
[   10.147075] modprobe: page allocation failure: order:0, mode:0xd2
[   10.147078] Pid: 263, comm: modprobe Not tainted 3.2.0-gentoo #5
[   10.147079] Call Trace:
[   10.147082]  [<ffffffff810a34d2>] ? 0xffffffff810a34d2
[   10.147084]  [<ffffffff810c7f34>] ? 0xffffffff810c7f34
[   10.147085]  [<ffffffff810c7cbd>] ? 0xffffffff810c7cbd
[   10.147087]  [<ffffffff8106b116>] ? 0xffffffff8106b116

[   10.147095]  [<ffffffff8106b3db>] ? 0xffffffff8106b3db
[   10.147096]  [<ffffffff8106b548>] ? 0xffffffff8106b548
[   10.147098]  [<ffffffff810dc00f>] ? 0xffffffff810dc00f
[   10.147100]  [<ffffffff8106ba70>] ? 0xffffffff8106ba70
[   10.147101]  [<ffffffff813de0fb>] ? 0xffffffff813de0fb


The full dmesg is listed in http://pastebin.com/Hs5x1Raz
And the kernel config is here http://pastebin.com/0HEZPcCx

I copied the kernel config file from kernel 3.1.6 directly, and no such issue is existed under kernel 3.1.6.

However, the system is still functioning under 3.2.0, and I havent noticed any issues so far.

Any thoughts?

[ISSUE SOLVED]
Code:
CONFIG_EXPERT=y
CONFIG_KALLSYMS=y

or
Code:
CONFIG_EXPERT=n

Hi i13m,

if the issue does not exists in 3.1.6 kernel so maybe there's something with 3.2.0 version. We must remember that it's not stable yet :)

BR,

Most helpful. I wondered what I had done wrong for about 3hours! There are also problems with Virtualbox on this kernel.

I noticed the same bug with 3.4.5 on ~amd64:
Code:
[kernel] cfg80211: Calling CRDA to update world regulatory domain
[kernel] warn_alloc_failed: 4 callbacks suppressed
[kernel] vmalloc: allocation failure: 0 bytes
[kernel] modprobe: page allocation failure: order:0, mode:0xd2
[kernel] Pid: 3643, comm: modprobe Not tainted 3.4.5-gentoo #5
[kernel] Call Trace:
[kernel]  [<ffffffff810a2095>] ? 0xffffffff810a2095
[kernel]  [<ffffffff810c71e8>] ? 0xffffffff810c71e8
...
However this non-debug output might not be useful. This happend when I modprobe'd rt73usb with all the dependencies. This is also solved by only adding CONFIG_KALLSYMS=y to the kernel which I found here.
Is it worth adding this bug to our bugzilla or is there already some upstream bug report? I'm not into the kernel mailing lists..
