I downloaded the latest Debian 9 live usb with nonfree driver and burned it to a USB drive. I loaded the live system on an old ASUS X71SL. I managed to run the live and then install the system. The debian system was able to boot fine. After rebooting in Windows 7 and applying a Windows update the Debian system hanged on boot. In particular starting in Debian recovery mode it seems to hang after these two messages:
zswap: loaded using pool lzo/zbud
[ 3.651373] ima: No TPM chip found, activating TPM-bypass!
I tried to run the live USB and also that one hanged at the same point.
The last time I managed to boot I created a swap partition on a logical partition of the disk. Can this be the cause? Can it be that also the live tries to use the swap and it hangs?
