Hi,
I am running linux-2.4.3 on a Dell dual PIII machine with 128M memory.
After the machine runs a while, dmesg shows,
__alloc_pages: 4-order allocation failed.
__alloc_pages: 3-order allocation failed.
__alloc_pages: 4-order allocation failed.
__alloc_pages: 4-order allocation failed.
__alloc_pages: 4-order allocation failed.
__alloc_pages: 4-order allocation failed.
and sometime the system will crash. I looked into the memory info,
there still has some free physical memory (20M) left and swap space is
almost not in use. (250M swap)
I didn't have this problem when I ran 2.4.0 (I even didn't see it on
2.4.2) could anybody tell me what's wrong or where should I look into this
problem?
Thanks,
Alex

Feng,
Which apps are you running when this happens ?
Thanks

It looks like the X consumes most of the memory (almost used up all the
physical memory, more than 100M), it uses NVidia driver. I was also
running pppoe but that took less memory.

You're probably using the NVidia provided driver module, right?
Try it without it and the "nv" driver.

Yes I am running nvidia module. i tried nv, X use less memory but nv
doesn't give me the NV_GLX extension, xlock will crash for some 3d mode.

In this case you should report any kernel problems you see to NVidia
first, except if you can also reproduce them without the nvidia module.

The problem is I didn't see those error message on 2.4.2 or 2.4.0, only on
2.4.3. That's the reason I posted the question here. Maybe I will try
2.4.4
Thanks all for you guys!

I am seeing this as well on 2.4.3 with both _get_free_pages() and
kmalloc(). In the kmalloc case, the modules hang waiting
for memory.

Would adding __builtin_return_address(0) to the warning help locate?

One possible source of this hang is due to the change below in
2.4.3, non GPF_ATOMIC and non-recursive allocations (PF_MEMALLOC is set)
will loop until the requested continuous memory is available.

Thanks for the suggestion. but where to get pre-2.4.4 kernel? when I
looked into the kernel traffic mail list, peoples are talking about 2.4.4,
but i checked kernel.org, the lastest one i found is 2.4.3
regards,
Alex

Hi,
I got the error __alloc_pages: 4-order allocation failed in a module that uses and frees a lot of pages.
Basically, I am trying implement a page cache for the module. First, I keep allocating pages using page_cache_alloc() until it fails, then I free a whole bunch of pages using freepages((unsigned long)page_address(page))
Would anyone please give me some advice about how to solve this problem?
Thanks a lot.

You ran out of memory, ie. there were no more free blocks of 16
consecutive pages available in the system. This is what happens on a
system with little memory or which is loaded with memory intensive
applications.

I'm seeing the same thing here on a machine with 256 MB RAM and 1.5
gigabytes of swap. There is no chance I am using anywhere near that
much virtual memory.
Something is wrong with the MM in 2.4.6-pre9.

David,
The messages are "harmless". The SCSI layer is trying to allocate big
chunks of memory (for the scattergather tables IIRC) just as an
optimization.
If its not possible to allocate big chunks, the SCSI code will use lower
order allocations. (smaller chunks)
