Hello,

Running 2.6.19.1 on AMD64.

While copying some files on an ext3 partition, I got this in the logs:

EXT3-fs warning (device sdd2): dx_probe: Unrecognised inode hash code 232

Yeah, I know it's tainted - just wanted to hear if anyone saw this one before. 
System seems to be fine otherwise, I'll run a fsck on the filesystem lateron.
