Hi all,
I try to do hypercalls but I always have a kernel panic that I don't understand.
I have Scentific Linux 6 installed on kvm and my computer has ubuntu.
I try to modify the SL6 kernel to do hypercalls.
I have a function in that kernel which check all syscalls in the VM.
When I put the hypercall at the beginning of this function, it perfectly works,
but when I try to put it in the middle of the function I have a kernel panic
with this
error:
"divide error: 0000 [#1] SMP
...
[<ffffffff813f8cdd>] panic+0x78/0x137
[<ffffffff813fcb94>] oops_end+0xe4/0x100
[<ffffffff8101021b>] die+0x5b/0x90
[<ffffffff813fc444>] do_trap+0xc4/0x160
[<ffffffff8100df2f>] do_divide_error+0x8f/0xb0
[<ffffffff811f974c>] ? my_function+0xdc/0xe70 "
Could you have any suggestions ?
With regards,
Emilie
