Hi Colin,
Thanks for the well-decoded report, but unfortunately I haven't been
able to figure out how the dentry list is getting trashed. Oopses like
this have been reported for a while, but the pattern still eludes me.
Possibly a stray pointer that happens to hit the dentry?
If the cause doesn't get tracked down soon, I may write a dentry list
verifier to check the lists at frequent intervals. As it stands, the
list could have been corrupted quite a while before the oops.
Regards,
Bill
