SPI transactions never finish (IDFGH-4825)

[KaeLL]

Environment

• Module or chip used: ESP32
• IDF version: v4.1
• Build System: Make
• Compiler version: 8.2.0
• Operating System: Linux
• Power Supply: external 5V

Problem Description

I have a custom board with 2 SPI-based peripherals, both of which share the VSPI bus. I'm having an issue in which the SPI stops working intermittently, regardless of the transaction type or peripheral, although apparently at the same stage of the transaction.
Interrupt transactions stop here (waiting for this) and polling transactions here (which leads to here) and sometimes while trying to acquire the bus for the transaction, as shown below. Both are basically the turning point to the end of each SPI transaction, and this similarity invites the belief in a correlation between the issues.
The workload on Core 0, other than IDF defined stuff, is basically the BLE Controller + occasionally non-pinned tasks like LwIP and MQTT, which leads me to believe spi_intr isn't being starved. Calling spi_bus_initialize on the other core didn't help. I use the transaction wrappers spi_device_{polling,}transmit, which are themselves wrapped by a bus-wide mutex, so I guess that also takes thread-safety issues out of the table.

Let me know of any other tests I should perform and details I can provide other than the code, ELF and complete coredump publicly (NDA).

I performed a test similar to what you had recommended, replacing logs with an event group
KaeLL@8fa0af7
which consistently shows the value 0x38, meaning POSTED is marked but RAN and ISR_ENA aren't, as if enabling the ISR sometimes fails (the simpler explanation, though I'm just assuming).
The test is a modified version of my app (line 53 commented out, ofc) with the code for my other SPI device (TRF7970A NFC, whose current implementation can't be shared, but if deemed necessary, I can port TI's reference driver) with nothing fancy on the SPI:

ESP_ERROR_CHECK( spi_bus_add_device(
		VSPI_HOST,
		&( const spi_device_interface_config_t ) {
			.command_bits = 3,
			.address_bits = 5,
			.spics_io_num = SLAVE_SELECT_PORT_SET,
			.clock_speed_hz = SPI_MASTER_FREQ_20M / 4,
			.mode = 1,
			.queue_size = 1,
			.cs_ena_pretrans = 1,
		},
		&trf_hdl ) );

Do you have any tips on taking this test a step further in order to isolate the problem? Btw, as indicated on the linked fork of IDF, the test was performed on latest master as of right now (21359bf)
