No change on my side:

=== CL_PROGRAM_BUILD_LOG ===
  Preferred work group size multiple (kernel)     <getWGsizes:1980:
create kernel : error -45>
  Warp size (NV)                                  32
  Max sub-groups per work group                   0


And the strace output section:


ioctl(5, _IOC(_IOC_NONE, 0, 0x22, 0), 0x7ffe9d70f980) = 0
ioctl(4, _IOC(_IOC_READ|_IOC_WRITE, 0x46, 0x29, 0x10), 0x7ffe9d70fa40)
= 0
mmap(0x205a00000, 2097152, PROT_NONE,
MAP_PRIVATE|MAP_FIXED|MAP_ANONYMOUS, -1, 0) = 0x205a00000
munmap(0x7f3676d9e000, 2494464)         = 0
ioctl(5, _IOC(_IOC_NONE, 0, 0x1a, 0), 0x7ffe9d70fd80) = 0
ioctl(4, _IOC(_IOC_READ|_IOC_WRITE, 0x46, 0x2a, 0x20), 0x7ffe9d70ebe0)
= 0
write(1, "  Preferred work group size mult"..., 4096  Preferred work
group size multiple (kernel)     <getWGsizes:1980: create kernel :
