Subject: page allocation failure. order:0, mode:0x20
Date: Fri, 19 Mar 2004 19:38:08 +0530 [thread overview]
Message-ID: <200403191938.09026.naveenb@cisco.com> (raw)
While testing linux-iscsi-4.0.1.1 driver on linux kernel version 2.6.3, my
system's console was floded with follwoing message:
"page allocation failure. order:0, mode:0x20"
Is this a known problem in linux kernel version 2.6.x ?
Is there any patch available for this problem ?
