NM10: SYS_RESET# did not reset CPU?

[AFahe]

Hi. Can anyone comment on under what conditions (if any) asserting SYS_RESET# on the NM10 may not reset a Atom N2800 CPU? Ran into one instance whereby the N2800 CPU was hung, and asserting SYS_RESET# did not reset it, with a full power cycle required. SYS_RESET# continues to function as expected otherwise. The default mode of the BIOS is to issue a hard-reset, i.e., PLTRST# is asserted along with SYS_RESET# .

Thanks!
