It hangs about three minutes on "welcome" screen with the blue background, while previously the total boot time was less than a minute. The issue only happens in TCG mode (not with KVM) and also happens with the current master which includes the uring patches (7d3660e7). I can reproduce this issue with a clean XP install with no flags other than `-m 2G`. After booting, the performance seems to be normal.
