Your latest i2cctrl driver install OK but after about some seconds BSOD 50 appears:
20260621-114642.jpg

This is what Copilot said about your BSOD:

That blue screen you’re seeing — PAGE_FAULT_IN_NONPAGED_AREA (STOP 0x00000050) — means a kernel‑mode driver or system component tried to access invalid memory. In your context, since you’re testing your I²C controller driver, this BSOD almost certainly originates from a bad pointer or MMIO access inside your backend (for example, dereferencing devctx->MmioBase before mapping or writing to an invalid offset).

Here’s how to narrow it down:

🧩 Likely causes

Invalid MMIO base — MmioBase not yet mapped when IntelReadReg or IntelWriteReg runs.

Null devctx — a failed allocation or uninitialized FDO context.

Incorrect BAR offset — writing to a register that doesn’t exist on the ES controller (e.g., LPSS‑only offsets).

Accessing pageable memory at IRQL ≥ DISPATCH_LEVEL — common if ISR/DPC touches nonpaged data incorrectly.

Removing the code will get you directly back to error 31. The backend is still hardware specific...

I'm sorry, but I have to wrote your attention:

  • do not quote the entire post, select only important lines using e.g. ... ...
  • do not quote entire logs or other things, e.g. what AI wrote - select important lines from them
  • test your drivers before posting public
  • if you need to post the entire log, use sites designed for this purpose, e.g. pastebin.com

@reboot12 Enable kernel memory dump from XP's registry (offline). Boot with i2cctrl set from manual to disabled, enable and disable from device manager again after service is enabled through serviwin/etc. Now on BSOD you should have a prompt for MEMORY.DMP.

With what hardware? I only have ASUS x509FA.

Sorry, but if you publish a driver, e.g. on github, you should first test it on at least several computers.

I'm not interested in your Asus x509FA laptop. I would like to use I2C drivers on other computers.

Atleast give me the info of the models that you have.

Yes, now there is no BSOD 50 anymore, but your drivers probably don't do the job because I still can't install the sound driver:
I2-C-not-help.png

Hold on, what service does the Intel SST Audio Device driver even use, hardware ID? That's very important information.

I need your i2cctrl.log btw.
