Message-ID: <CAAA8XhMf9BhZP5csLfGVVbQxN7Uqh-+R6aqCLfezdiTECaRRjg@mail.gmail.com> Date: Thu, 26 Jan 2012 13:57:34 -0200 From: Kelbel Junior <jymmyjr@...il.com> To: Christoph Hellwig <hch@...radead.org> Cc: linux-kernel@...r.kernel.org, xfs@....sgi.com Subject: Re: XFS problem Well, in 24/01 i upgrade to the kernel 3.2.1 in one server and forgot read my emails...until now it's running without problems. Then, yesterday i put kernel 3.2.1 on another server and this morning a several same messages "server013 kernel: XFS: possible memory allocation deadlock in kmem_alloc (mode:0x250)" and delays. (without call trace because i forgot to apply that patch with dump_stack) Now i applied the dump_stack and the latest patches that you sent. I'm trying to discover what triggers this bug, to help in a solution... I tell you any news *** Some useful information: # mount /dev/sdb1 on MOUNTPOINT type xfs (rw,noatime) But in some cases i use RAID and mount the partition with the following settings (and happen the same problem): /dev/mapper/server012_vg-server012_vol on MOUNTPOINT type xfs (rw,noatime,nodiratime,inode64,nobarrier) HD model: Seagate ST31000528AS -- Barracuda 7200.12 SATA 3Gb/s 1TB Hard Drive I work in a cache solution company, so I/O performance is very important in our context.
