Updated by Evgeny Novikov almost 3 years ago

  • Priority changed from Normal to Urgent

Likely due to this issue all modules of the newest versions of the Linux kernel couldn't be verified.

#2

Updated by Anton Vasilyev almost 3 years ago

It seems that there is bug in linux kernel with return from void function.

static inline void paravirt_write_msr() {
    return PVOP_VCALL3();
}

#3

Updated by Evgeny Novikov about 2 years ago

  • Status changed from New to Closed

I fixed the issue in d95cdf0 and added corresponding test cases there as well.
