mystery solved: on 10.04 I had: GRUB_CMDLINE_LINUX_DEFAULT="nolapic_timer nohz=off highres=off nosplash"
when VB was still more brittle wrt APIC emulation replaced by GRUB_CMDLINE_LINUX_DEFAULT="nosplash" update-grub, reboot, works - with lousy latency, but with RTAI -m what should have given a clue was: 10.04: [ 51.731109] RTAI[sched]: hard timer type/freq = APIC/0(Hz); default timing: periodic; linear timed lists. 8.04: [ 117.038945] RTAI[sched]: hard timer type/freq = 8254-PIT/1193180(Hz); default timing: periodic; linear timed lists. ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
