Jeremy, 

Because the problem angle has changed to the file system and kernel I/O, and 
just to provide aditional info, I'll show you our mount options:

lvmp		-> (reiserfs)   usrquota,grpquota,acl,user_xattr 
lvgroups	-> (reiserfs)   grpquota,acl,user_xattr 
lvhomes	-> (reiserfs)   usrquota,acl,user_xattr 

We were using "noatime" option too, but now is disable, and nothing has 
changed.

Note that it is connected to an external storage (EVA 5000) with qla2312 fiber 
channel. The qla2xxx module is being loaded with the following options:

options qla2xxx qlport_down_retry=30 ql2xfailover=1 ql2xloginretrycount=30 
ql2xlbType=0 

Hope this could be useful to give us a clue!

saludos, 
Martín
