Hi, My wifi connections to our work enterprise wifi started failing after the update of wpa_supplicant to 2.7, the issues appear in the kernel logs (attached), mainly : WARNING: CPU: 7 PID: 25138 at ../drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c:5122 brcmf_cfg80211_set_pmk+0x2f/0x40 [brcmfmac] I did a git-bisect and it appears the following commit introduced the issue: https://w1.fi/cgit/hostap/commit/?id=0ff08f96367eaedd7f0554c62d59b4a713a584b2 Reverting that patch seems to make the WPA enterprise connections work again but not sure if it's the right thing to do. Let me know if there is anything else I can help with to fix the issue. Thanks ! Amine
