If you weren't connecting anything at the time, it's possible t= hat a device is buggy and had disconnected by itself a moment earlier, but the = log is too short to tell. Not sure why it crashed. It looks like there were two attempts 6 seconds ap= art and no crash on the first attempt. It's unlikely that xhci was NULL near the end of the function. If it were, there were several opportunities to crash earlier. The call to xhci_mod_cmd_timer() in the next line dereferences xhci->cur_cmd, which is perhaps more suspicious. --=20 You may reply to this email to add a comment.
