Hi all,

  my bittorrent box running 2.6.12-git5 (AMD K7-800,
  256MB RAM, fairly recently updated FC3) decided to
  oops  a few hours ago. On the console I had a very long
  trace before the actual lockup, but I didn't write it down
  (it had ide_dma_<xx>_request  and bh_<xx> calls as
  main part of the trace, though it took up all of my screen
  and more so I can't tell where the EIP was).

At reboot however I have an oops with EIP in free_block
 very likely happened after/during an updatedb run which
 very closely resembles this report that hit isofs in 2.6.9-rc2:

The only thing running on the box at that time was a
 download of a 8GB torrent with bittorrent from the
 FC3 bittorrent-4.1.1-2.1.fc3.rf package.

Attached the oops trace and the decoded oops
 after I edited the trace to remove the timed printks
 and ran it through ksymoops 2.4.11.

kernel isn't running CONFIG_DEBUG_SLAB but
 if you think this is a legitimate slab bug I'll later
 update to the current -git kernel and enable the
 slab debugging.

Thanks,
