always crashes (interrupt watchdog timeout) in a spinlock when doing "heavy" Ethernet traffic on a wt32-eth01 #10557

Board

WT-ETH01

Device Description

This is a regular esp32 with an ethernet-port bolted on.

Hardware Configuration

There's an SD-Card reader attached to pins 

#define pin_SD_MISO 12
#define pin_SD_MOSI 13
#define pin_SD_SCLK 14
#define pin_SD_CS 15

Version

v3.0.6

IDE Name

PlatformIO

Operating System

Ubuntu Linux 24.10

Flash frequency

default

PSRAM enabled

no

Upload speed

115200

Description

The problem occurs with an iSCSI target running on the ESP32. During setup (DHCP, iSCSI logon) all is good. Yet when regular i/o occurs (e.g. reads and writes to the device), an interrupt watchdog happens.

Sketch

Sofar I haven't been able to make a smaller sketch showing the behaviour.
The same 'sketch' runs fine on teensy and on linux (yes).

Debug Message
