Package: linux-image-2.6.18-4-686
Version: 2.6.18.dfsg.1-12
Severity: normal


I have been using sshfs over fuse for quite some time without
problems.  Noticed a high load this morning, and found the oops below.  
Known fixed issue upstream: http://lkml.org/lkml/2007/1/29/210  ??

I'm not sure of what triggered this oops.  At the time of the fault,
the system was pretty idle, and I don't think my net connection or the
ssh connection went down at the time.

Changes: 
 linux-2.6 (2.6.18.dfsg.1-14) stable; urgency=high
 .
   [ dann frazier ]
   * [bluetooth] Fix panic caused by race between RFCOMM socket layer and
     RFCOMM TTY layer. Thanks to Mikko Rapeli. (closes: #394742)
   * Add support for AMD/ATI SB700 hardware, see #429622
   * Add support for Intel ICH9 controllers, see #435877
   * [hppa] remove misuse of global_ack_eiem, fixing a race condition that
     resulted in frequent lockups on SMP systems. See: #435878
 .
   [ Frederik Schüler ]
   * Add support for 3ware 9650SE controllers. (closes: #402562)
 .
   [ dann frazier ]
   * bugfix/reset-pdeathsig-on-suid-upstream.patch
     Update fix for CVE-2007-3848 with the patch accepted upstream
   * Fix ipv6 rfc conformance issue introduced in 2.6.18.dfsg.1-13 by the
     fix for CVE-2007-2242. Thanks to Brian Haley for the patch.
     (closes: #440127)
   * Fix a minor denial of service issue that allows local users to disable
     an interrupt by causing an interrupt handler to be quickly inserted/removed.
     This has only been shown to happen with certain serial devices so can only
     be triggered by a user who already has additional priveleges (dialout
     group). (closes: #404815)
   * Fix a BUG in fuse_ctl_add_dentry by resetting the dentry counter in
     fuse_ctl_kill_sb(). (closes: #427518)
   * Fix a regression introduced by the intel_agp changes in -13 that caused
     boot-time hangs on large memory systems. (closes: #438458)
