Hi,

I'm using wpa_supplicant v2.4 on custom x86 platform (VIA board). When
I'm trying
connect to AP with WPA2 and AES encryption I cannot connect due to the
errors like (with TKIP it works fine):

selftest for CFB failed - see syslog for details

and when inspecting syslog I found :
Libgcrypt warning: AES-CFB-128 test failed (plaintext mismatch, parallel path)

I'm using libgcryp 1.6.3 and whole system is build using yocto.
Compared to my laptop with same version of wpa_suplicant (v2.4) but
libgcrypt was 1.6.5 it works fine here . Could it be some missing
configuration or any pointer where to look? I have enabled in kernel
config CONFIG_CRYPTO_AES_NI_INTEL=y and also
CONFIG_CRYPTO_DEV_PADLOCK_AES=y. Thanks a lot.

BR,

marek
