wake up deep sleep from timer with rtc clock set at 8MHz /256 (IDFGH-7311)

[ElieSKickMaker]

Hello,

I'm using the sntp example . When by menuconfig, I set :

• CONFIG_RTC_CLK_SRC = Internal 150KHz , it's working and the cpu is waked up after 10 s
• CONFIG_RTC_CLK_SRC = Internal 8MHz, it's not working, the cpu is never waked up.

Do I miss something ?

@ElieSKickMaker
Which esp-idf version are you using?
The fix should be available in v4.4 and newer branches. (But the v4.3 still needs fix)
This is duplicated of #8007

#9455

The cpu waked up when use 8MHz RTC in my case.
But the sleep time is more than 3 minutes and printed time is 10 s after the before printed time.
