we should deprecate this solver/kernel, because we would use following instead:
ConvHipImplicitGemmBwdDataV1R1Xdlops
gridwise_convolution_backward_data_implicit_gemm_v1r1_xdlops_nchw_kcyx_nkhw.cpp

[atamazov]

Good news. Just in case -- if we need to quickly disable it, then changing the default value of respective env variable will do the job ( IsDisabled() -> !IsEnabled()).

[aserio]

@zjing14 and @asroy, what is the status of this issue?

[aserio]

@zjing14 please close if new PR resolves this issue

[atamazov]

Workaround by #457. Full blown fix is not yet implemented, so let's keep it open (until W/A is removed) but lower priority. And this is not a bug anymore.

@zjing14 Is this still an issue? If not, can we close this ticket? Thanks!

[huanrwan-amd]

Hi @atamazov, is it OK to close the issue? As we are not observing the failure in the original test: "failed due to requirement 'K % 8 == 0' "K needs to be in multiple of KPACK""
