I have an AMD RX6400 and all gpu wus crashes after few seconds:

gpu_search_init: using OpenCL device "gfx1034"
gpu_search_init: kernel build failed:
ld.lld: error: undefined hidden symbol: jacobian_batch_to_affine
Error: Creating the executable from LLVM IRs failed.

gpu_search_init failed (platform 0, device 0) -- no usable OpenCL device?
2026-09-29 22:16:27 (21260): called boinc_finish(1)

Is too much little my gpu?

Found it, thanks for the exact error message -- that's what made this fixable. Your RX6400 (gfx1034) isn't too weak, it hit a real bug in our OpenCL kernel: some internal helper functions weren't declared correctly, and AMD's compiler for your GPU (unlike most others) refused to link the result because of it. Nothing wrong on your end.

Fixed and deployed just now. A new OpenCL app version has been published for Linux/Windows/ARM; your client should pick it up automatically on its next work request. If it still crashes the same way after that, please post the new log here.

Now seems solved the gpu app!!

It is wonderful to hear that the GPU application issues seem to be solved! We genuinely appreciate you taking the time to contribute to our volunteer computing efforts. Thank you for your participation.
