  8. RDR_FILE_SYSTEM (27)
  9.     If you see RxExceptionFilter on the stack then the 2nd and 3rd parameters are the
  10.     exception record and context record. Do a .cxr on the 3rd parameter and then kb to
  11.     obtain a more informative stack trace.
  12.     The high 16 bits of the first parameter is the RDBSS BugCheck code, which is defined
  13.     as follows:
  14.      RDBSS_BUG_CHECK_CACHESUP  = 0xca550000,
  15.      RDBSS_BUG_CHECK_CLEANUP   = 0xc1ee0000,
  16.      RDBSS_BUG_CHECK_CLOSE     = 0xc10e0000,
  17.      RDBSS_BUG_CHECK_NTEXCEPT  = 0xbaad0000,
  18. Arguments:
  19. Arg1: 00000000baad0080
  20. Arg2: ffffe1012638ee78
