Problem on Suspend to RAM vs ext3

Problem on Suspend to RAM vs ext3

[Francesco VIRLINZI]

Hi all
I have a problem whit my embedded system on kernel 2.6.23.17.
When I call more and more time the suspend on memory than (some time)
 the root file system on ext3 has some problem during the resume.
With google I understood it's a known issue but I didn't understand if 
there is a solution.
Could you give me an help?
Thanks
Regards
 Francesco

P.S.: here the dmesf I have:

What kind of a problem is this exactly?

Thanks,

Hi Rafael
It seems there is a problem with the journal FS.
As you can see in the following dmesg but at the moment I don't know 
more than that.
Do you know if someone has an issue like that?
Or is it my personal problem (never raised before)?
Thanks
Regards
 Francesco

This is a problem with the SATA driver IMO.  There's a good chance it's been
fixed in one of the more recent kernels.

Please try 2.6.25.x.

Thanks,
Rafael
