Problem on Suspend to RAM vs ext3

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

Hi Rafael
I will try to update my kernel

Thanks for your support
