I get: this error message when using barriers on a scsi disk:

lost page write due to I/O error on sdb1
JBD: barrier-based sync failed on sdb1 - bisabling barriers

and I don't want them barriers bisabled :)

ext3 filesystem. reiser also disables barriers.

I have a "Adaptec AIC-7902 U320 (rev 3)" SCSI controller and the disk is a
SEAGATE ST373307LW.

It works on ide.
