Subject: [CRASH] crypto: virtio: crash when modprobing tcrypt on 5.5-rc7 / next-20200122
Date: Thu, 23 Jan 2020 11:10:00 +0100 [thread overview]
Message-ID: <20200123101000.GB24255@Red> (raw)
Hello
When modprobing tcrypt on qemu 4.1.0 I get a kernel panic on 5.5-rc7 and next-20200122
qemu is started by:
/usr/bin/qemu-system-x86_64 -cpu host -enable-kvm -nographic -net nic,model=e1000,macaddr=52:54:00:12:34:58 -net tap -m 512 -monitor none -object cryptodev-backend-builtin,id=cryptodev0 -device virtio-crypto-pci,id=crypto0,cryptodev=cryptodev0 -append 'console=ttyS0 root=/dev/ram0 ip=dhcp' -kernel /var/lib/lava/dispatcher/tmp/41332/deployimages-td18675m/kernel/bzImage -initrd /var/lib/lava/dispatcher/tmp/41332/deployimages-td18675m/ramdisk/rootfs.cpio.gz -drive format=qcow2,file=/var/lib/lava/dispatcher/tmp/41332/apply-overlay-guest-icy4k1ol/lava-guest.qcow2,media=disk,if=ide,id=lavatest
