Re: data corruption with 2.4.25 and datalogging patches

Hello,
I think It's not a memory problem. I have run memtest for more than 24 hours 
and the memory is OK. 
We use the best memory in the market (Kingston). When a system 
fails we check hardware devices first. If we find a hardware problem we 
usually don't check for software problem. 

I have other system with reiserfs corruption. I send you attached reisefsck 
output for  'reiserfsck --check' and 'reiserfsck --check --fix-fixable'

Regards,

Paco
