Hello,

Nov 10 18:53:46 Inode i_mmap ring corrupted

As the "Inode i_mmap ring corrupted" message continues to appear I rebooted
shortly after that.

Is this a known bug - is there a patch for it ?

If futher info on hardware etc. is needed, i can provide it.

Please reply also directly to me.

Thanks for any help.
