Description Ritesh Raj Sarraf 2010-01-05 09:14:32 UTC 
This bug is partially related to bug #14206

In the above mentioned bugzilla, I mentioned a workaround script which reloads the ipw2200 driver on resume.

Today, during resume, following is the error I see in dmesg and the device was not loaded.

Later, manually reloading the driver worked as before. I am not sure if this can be reproducible again.
Comment 1 John W. Linville 2010-01-05 14:23:18 UTC 
Are you using IBSS (i.e. Ad-Hoc) mode?  Which block allocator (e.g. SLAB, SLUB) are you using?
Comment 2 Ritesh Raj Sarraf 2010-01-06 03:22:38 UTC 
No. I am using the Managed Mode.

I am using the SLUB allocator.

fix patch

[PATCH] libipw: split ieee->networks into small pieces

The ieee->networks consists of 128 struct libipw_network entries. If
we allocate this chunk of memory altogether, it ends up with an
order 4 page allocation. High order page allocation is likely to fail
on system high load. This patch splits the big chunk memory allocation
into small pieces, each is 344 bytes, allocates them with 128 times.

Zhu Yi, did you ever submit that patch on the mailing list?  Ritesh, did you ever test it?

No. I have not tested the patch. And have not seen the bug again. I still am running on the 2.6.32 kernel
Comment 6 John W. Linville 2010-08-13 15:54:45 UTC 
Sounds like it can't be reproduced...closing.
