Re: Problem on Suspend to RAM vs ext3

[Francesco VIRLINZI <francesco.virlinzi@st.com>]

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
