[f-nsp] MLX load monitor failed after factory reset

["Rolf Hanßen"]

Hello,

just wanted to factory-reset 2 MLX-4 routers.
I did a erase startup-config and reloaded.

Now one MP hangs seconds after tuning on power:

NetIron XMR/MLX Boot Code Version 5.6.00
..MP.
Enter 'a' to stop at memory test
Enter 'b' to stop at boot monitor
..BOOT ERR: load monitor failed -- HANGING

I can enter the memory test, pressing 'b' does not help, it still crashes.

Inserting it as second MP to the working second box shows that message here:

NetIron MLX-4 Router#rw_isr_present is called:
OLD: pwr = 000000fc, fan = 00000600, lp = 0000fff0, lp1 = 00000000, sfm =
000c0000, sfm1 = 00000000, mnm = 00100000
NEW: pwr = 000000fc, fan = 00000600, lp = 0000fff0, lp1 = 00000000, sfm =
000c0000, sfm1 = 00000000, mnm = 00000000
rw_isr_present: mnm_present_reg_val = 00000000, g_rw_mnm_present_reg_val =
00100000
rw_isr_present: send ITC_MSG_TYPE_MBRIDGE_INT1 to scp_task
Standby MP inserted

Console output of the "bricked" is still the same.
show modeule status is "Standby(Reboot State)"

Any clues how to fix that. The device has no vendor support.

kind regards
Rolf
