That's purely an in-memory data structure, it shouldn't be affected by anything on disk. You could try a forced fsck just to be sure, but it doesn't sound like there's a corruption on disk here. (There *is* a variant of the revoke list that is read from disk, but that's only used during log replay, which isn't active in your oops traces.) > if the box passes the boot, everything is peachy. > No filesystem corruption of any kind. Sounds to me like you're getting corruption in a repeatable address somewhere at boot time that just happens to be hitting the revoke list early on. I saw something like this once before, except it was on a buffer_head list. Debugging, I was able to identify that the *previous* entry of the list was always exactly at the 16MB mark in memory, and the list pointers there were getting corrupted. Turned out to be a bad BIOS that was trapping a PCI bus operation, setting up a pte for some internal workspace, restoring it on exit back to the OS but forgetting to flush the tlb. Adding a tlb flush after various PCI ops fixed it completely. Similar footprint to yours: a crash shortly after boot in a specific data structure but with pretty random VAs, and at random points in the bh walking code. The revoke code hasn't changed in *ages*, and I've never seen a report of that list getting corrupted before. I suspect the fs is just an innocent victim here.
