## Summary With `RTEMS_DEBUG` enabled the PC ATA driver asserts with a failure because a node's link pointer is not set to `NULL`. The assert is: ``` assertion "_Chain_Is_node_off_chain( the_node )" failed: file "../../../cpukit/include/rtems/score/chainimpl.h", line 691, function: _Chain_Append_unprotected ``` A back trace is: ``` (gdb) bt #0 0x00162c55 in bsp_reset (source=source@entry=RTEMS_FATAL_SOURCE_ASSERT, code=code@entry=1872624) at ../../../bsps/i386/pc386/start/bspreset.c:39 #1 0x00161b15 in bsp_fatal_extension (source=RTEMS_FATAL_SOURCE_ASSERT, always_set_to_false=false, code=1872624) at ../../../bsps/shared/start/bspfatal-default.c:213 #2 0x001189b3 in _User_extensions_Iterate (arg=arg@entry=0x1c92b8, visitor=0x118900 <_User_extensions_Fatal_visitor>, direction=CHAIN_ITERATOR_FORWARD) at ../../../cpukit/score/src/userextiterate.c:194 #3 0x0011321f in _User_extensions_Fatal (error=1872624, source=RTEMS_FATAL_SOURCE_ASSERT) at ../../../cpukit/include/rtems/score/userextimpl.h:467 #4 _Terminate (the_source=the_source@entry=RTEMS_FATAL_SOURCE_ASSERT, the_error=the_error@entry=1872624) at ../../../cpukit/score/src/interr.c:66 #5 0x001077ec in rtems_fatal (fatal_code=1872624, fatal_source=RTEMS_FATAL_SOURCE_ASSERT) at ../../../cpukit/include/rtems/fatal.h:160 #6 __assert_func (file=file@entry=0x189a64 "../../../cpukit/include/rtems/score/chainimpl.h", line=691, func=0x1a0378 <__func__.0> "_Chain_Append_unprotected", failedexpr=0x189a3c "_Chain_Is_node_off_chain( the_node )") at ../../../cpukit/libcsupport/src/__assert.c:71 #7 0x0016c03d in _Chain_Append_unprotected (the_node=0x1cbbc0, the_chain=0x1aae4c <ata_ide_ctrls+44>) at ../../../cpukit/include/rtems/score/chainimpl.h:691 #8 0x0016c0dc in _Chain_Append_unprotected (the_node=0x1cbbc0, the_chain=0x1aae4c <ata_ide_ctrls+44>) at ../../../cpukit/sapi/src/chainprotected.c:99 #9 rtems_chain_append (chain=chain@entry=0x1aae4c <ata_ide_ctrls+44>, node=0x1cbbc0) at ../../../cpukit/sapi/src/chainprotected.c:97 #10 0x00160cb9 in ata_add_to_controller_queue (ctrl_minor=0, areq=0x1cbbc0) at ../../../bsps/shared/dev/ide/ata.c:540 #11 0x00160ea1 in ata_io_data_request (ata_dev=<optimized out>, req=0x1c9450) at ../../../bsps/shared/dev/ide/ata.c:228 #12 ata_ioctl (dd=0x1bee44, cmd=3222815233, argp=0x1c9450) at ../../../bsps/shared/dev/ide/ata.c:949 #13 0x00102f5e in rtems_bdbuf_execute_transfer_request (dd=dd@entry=0x1bee44, req=req@entry=0x1c9450, cache_locked=cache_locked@entry=true) at ../../../cpukit/libblock/src/bdbuf.c:1878 #14 0x001032c9 in rtems_bdbuf_execute_read_request (dd=dd@entry=0x1bee44, bd=<optimized out>, bd@entry=0x1bbe2c, transfer_count=transfer_count@entry=1) at ../../../cpukit/libblock/src/bdbuf.c:1994 #15 0x001044df in rtems_bdbuf_read (dd=dd@entry=0x1bee44, block=block@entry=0, bd_ptr=bd_ptr@entry=0x1c9558) at ../../../cpukit/libblock/src/bdbuf.c:2094 #16 0x00131f67 in rtems_bdpart_read_record (dd=0x1bee44, index=0, block=0x1c9558) at ../../../cpukit/libblock/src/bdpart-read.c:220 #17 0x00132190 in rtems_bdpart_read (disk_name=disk_name@entry=0x1ca62e "/dev/hda", format=format@entry=0x1c95dc, pt=pt@entry=0x1c9630, count=count@entry=0x1c95d4) at ../../../cpukit/libblock/src/bdpart-read.c:273 #18 0x00119a5e in rtems_bdpart_shell_main (argc=2, argv=0x1c9b30) at ../../../cpukit/libmisc/shell/fdisk.c:236 #19 0x0012dacd in shell_main_loop (shell_env=shell_env@entry=0x1c9ec8, interactive=interactive@entry=true, line_editor_output=<optimized out>) at ../../../cpukit/libmisc/shell/shell.c:1215 #20 0x0012ed18 in rtems_shell_main_loop (shell_env=shell_env@entry=0x1c9ec8) at ../../../cpukit/libmisc/shell/shell.c:1383 #21 0x0012ed38 in rtems_shell_task (task_argument=1875656) at ../../../cpukit/libmisc/shell/shell.c:1038 #22 0x00115adb in _Thread_Handler () at ../../../cpukit/score/src/threadhandler.c:164 #23 0xa5a5a5a5 in ??
