Good afternoon,

I am to report a kernel panic issue, related to rtl8192se module in kernel version 4.2.3. The problem occurs when placing the network adapter in AP mode through hostapd software. A few minutes after the start of hostapd daemon, the module fails, displaying the traditional screen failure. Below is the error message. Thanks in advance.

According to this bug report (bugzilla.kernel.org/show_bug.cgi?id=82761), it seems that you have VT-d enabled in your BIOS. What happens if you disable that?

And according to the commit to the qemu project below, realtek NICs are known to have certain quirks that cause problems with virtualization, even if you're not using virtualization directly but have certain features enabled in your BIOS.

My notebook is a little old, the BIOS is 2009 and does not have available updates, configuration options are minimal, unfortunately does not have option to disable the VT-d. Is there a kernel parameter that I can use during the boot to disable it? If so, I will be able to use the KVM or vbox after that?
