x86 Bisect script is currently down

Hi all,

During my vacation last three weeks, it seems to me that
my bisect script is down. After I am back from my holiday
this week, I found that the machine OS disk is totally down.

Please expect some time to bring that bisect script back. The
Test regression reporter is still running. (However, with quite
a few false positive for a long time due to timeout issue and
hard to fix unless I found other powerful machines.)

Thx,
Haochen
