Hi,

I have updated my -CURRENT kernel right after Jeff's changes to VFS.
FYI, I applied Soren's last ATA mkIII patch, although it doesn't seem
to be relevant here.

While mounting my USB key, I got the following panic :

%%%
  panic: lockmgr: unknown locktype request 0
  KDB: stack backtrace:
  kdb_backtrace()
  panic()
  lockmgr()
  vfs_hash_insert()
  deget()
  msdosfs_root()
  update_mp()
  msdosfs_mount()
  vfs_domount()
  vfs_donmount()
  kernel_mount()
  msdosfs_cmount()
  mount()
  syscall()
  Xint0x80_syscall()
  --- syscall (21, FreeBSD ELF32, mount), eip = 0x280c339f, esp = 0xbfbfe6dc, ebp = 0xbfbfed44 ---
%%%

A kernel dump is available.  Please contact me off-list if you need it.

Best regards,
