Hi slac, you're 100% right! Kernel panic is happening in guest machine (qemu), the -m 1G option solved my pb

I'm not familiar in booting big iso with qemu but playing and installing old Slackware distros within qemu-2.8

Still installed slackware-pre-1.0-beta and slackware-1.01 on a disk image with (pre-created) floppy images and using the
doinstall (installation program)
