[I've marked this bug for inclusion in our oneiric bug queue. While technically this bug has not been re-confirmed against oneiric, I feel it is worth continued development attention. We will need to ask that it be re-confirmed once oneiric is further along, perhaps once we get closer to alpha.]

[Bryce Harrington (bryce)]

I've noticed a couple other bugs with similar "CloseWellKnownConnections()" entries in their traces.

[Bryce Harrington (bryce)]

Failure seems to occur at this point in the code:

switch_to(int vt, const char *from)
{
    if (ioctl(xf86Info.consoleFd, VT_ACTIVATE, vt) < 0)
        FatalError("%s: VT_ACTIVATE failed: %s\n", from, strerror(errno));

[Bryce Harrington (bryce)]

Apparently failing in ioctl call trying to switch to vt 6. This is starting to look like a problem lower down than X. Kernel maybe?

[Žilvinas Valinskas (zval)]

see bug #441653, seems the same issue.
