Hi Dave,
Is this related to log buffer size when formatting and mounting as I am just
using the default 32KB buffer size?
Any pointers will be helpful.

Subject: kernel 2.6.22 pdflush consumes ~90% cpu
Hi,
I am currently working on an embedded platform involving XFS as the preferred
fs. Earlier, ext3 was used but now replaced with XFS. The unit is working fine
with ext3 but after replacing with XFS, I am seeing a few issues:
a) Occassionally I am getting the following error when we write files to the fs:
attempt to access beyond end of device
sda1: rw=0, want=10487141907480064, limit=9766912
I/O error in filesystem ("sda1") meta-data dev sda1 block 0x254200001abdf8
("xfs_trans_read_buf") error 5 buf count 4096
attempt to access beyond end of device
sda1: rw=0, want=10487141907480064, limit=9766912
I/O error in filesystem ("sda1") meta-data dev sda1 block 0x254200001abdf8
("xfs_trans_read_buf") error 5 buf count 4096
b) After running for about 20 to 25 minutes, the pdflush consumes about 90% cpu
and stuck there in D state:
Is there any similar issue seen with kernel 2.6.22? Am I missing any XFS
patches that could fix this?
Any pointers would be helpful.
Thanks,
Murali
