Products
G-Series; firmware 6.61.06.0009, 6.61.07.0010

Changes
Pressed and held for 8+ seconds (the Hardware Installation Guide recommends 5 seconds) the 'POWER OFF' button corresponding to a targeted IOM slot, in preparation for removing the IOM from that slot.

Symptoms
Unit reboot.

The current.log (5487) displays a "Task EDB BXS Resp(<address>) is suspended..." message with last reset cause "Fault(0x00000300)"; for example:
    <160>Sep 3 03:43:37 172.17.8.120-1 SIM[104439944]: hwutils.c(7536) 762 %%

The sysDmp (13650) file states "Task Name: EDB BXS Resp" and the diagnostic points to "faultbias"; for example:
