No. x86_udelay_tsc is initialized by time_init(), and time_init() is called before
smp_init(). The udelay implementation only multiplies with loops_per_jiffy,
therefore there is no oops on i386.

But could oops if the bios disables the TSC instruction - the first printk on
the secondary cpu happens before
