The issue is with p18245 running on intel arc b580.
In about 20 workunits, not a single one ended successfully.
Linux kernel: 6.17.0-14-generic
Driver: xe
Mesa: 26.1.0~git2602112334.b651fd90d2d~q~mesaaco15
OpenCL: 26.01.36711.4
No problem with the nvidia card, by the way. And the Intel works well with other projects.

Latest intel firmware nukes opencl compute.
Mine is running fine on fedora 43 driver 25.48

My B580 has the latest firmware available from fwupdmgr and performance is not impaired. The two WUs run today had about 3.1M PPD.

Wow! I haven't changed anything, but here it is my first successful p18245 workunit on Intel, after 20 failed: 827,2,12. Only 2.7M PPDs though.
However one swallow does not make a summer. We'll see.
BTW: my b580 loves projects 16773/4/5, instead. With them It goes up to 3.7M PPDs, even if the base credit is only 53.000. On the contrary, as an example, with p12137 and its base credit of 43.248, it stays low at about 2.5M PPDs.

On fwupd.org
https://fwupd.org/lvfs/search?value=b580 there is also a marginally newer firmware, but it's the intel standard so fwupdmgr ignores it (and I won't install it manually).
