esp-idf: Guru Meditation Error: Core 0 panic'ed (Interrupt wdt timeout on CPU0). (IDFGH-4630)

Hi,

Environment

• Module or chip used: ESP32-WROOM-32E
• IDF version: ESP-IDF v4.2-dirty
• SPI Speed: 80MHz
• SPI Mode: DIO
• SPI Flash Size : 8MB
• Watchdog config:
• UART ISR:

Problem Description

UART1 is connected to a 4G modem at 115200bps, and the communication uses AT commands.

When I use HTTP to download a file (approximately 1MBytes), every 512 bytes after the download is completed, it is stored in the internal flash that in the ESP32-WROOM-32E module. In this case, this Guru Meditation Error happens occasionally.

Please help check the crash log:
