Re: help with 2.4.18 oops - sorry was 2.4.16



Actually the previous error I reported was on a 2.4.16 kernel.

upgrading to 2.4.18 made it stop hanging the system and got us to the real 
error message:

kernel: journal_bmap: journal block not found at offset 6924 on sd(8,2)
kernel: Aborting journal on device sd(8,2).
kernel: ext3_abort called.
kernel: EXT3-fs abort (device sd(8,2)): 
ext3_journal_start: Detected aborted journal
kernel: Remounting filesystem read-only


any idea how we can recover from here? is there a way to rebuild an ext3 
journal?
