Hi, We have had issues with tboot 1.8.x and 1.9.4, and seeing garbage characters on the cmdline at the end. We've seen this on multiple different hardware types, different OSes(RHEL 7.3, Centos 7.2, SLES12sp2). We are using PXE boot in all the cases that I'm aware of.
It looks like we are passing tboot a good command line and then tboot passes control to the kernel, at which time the command line has the extra characters on it. TBOOT: verifying module " (tftp)/boot/sles12sp2/vmlinuz-4.4.21-69-default MAC=[snipped]... [...] crashkernel=256M"... TBOOT: OK : d6 ce 7b 29 41 a3 3a d9 3a b8 1a 69 55 88 9b 66 49 4c 80 66 TBOOT: verifying module " (tftp)/boot/sles12sp2/initrd-4.4.21-69-default"... Then it transfers control to the kernel. At this point the kernel shows that the cmdline it got is corrupted.
