Bug #1751

Updated by tuxillo almost 2 years ago

Hi,

During the boot process of the livecd (latest x86_64 ISO from
26-April-2010) on KVM, I get the following:

In sys/platform/vkernel64/x86_64/trap.c line 639 there's a comment:

"Invalid segment selectors and out of bounds %rip's and %rsp's can be
set up in user mode. This causes a fault in kernel mode when the
kernel tries to return to user mode. We want to get this fault so
that we can fix the problem here and not have to check all the
selectors and pointers when the user changes them."

Cheers,
Antonio Huete
