--- Comment #96 from Andreas Nordal 2011-07-10 15:20:30 UTC ---
The problem can not alone be caused by SMI latency.
I'm borrowing a Dell Latitude E6500 for a summer internship. It is probably a
little over a year old. It runs OpenSuse 11.4 flawlessly and looks sane in
rt-benchmark. However, it failed all tests that biosbits had to offer, in
particular, its maximum SMI latency was consistently ~8 times higher than my
previous record!

Testing SMI latency...
Warning: touching the keyboard can affect the results of this test.
Starting pass #1. Calibrating the TSC.
Starting pass #2. Wait here, I will be back in 15 seconds.
0 < t <= 1us; average = 80ns; count = 186281344
Times between first few observations: 116ns 113ns 101ns 90ns 90ns
100us < t <= 1ms; average = 331us; count = 31
Times between first few observations: 824ms 200ms 791ms 234ms 757ms
1ms < t <= 10ms; average = 3227us; count = 2
Times between first few observations: 10ms
Summary of impact: observed maximum latency = 4437us
SMI latency < 150us to minimize risk of OS timeouts FAIL
Risk of OS timeouts exists with this observed latency.
Summary: 0 passed, 1 failed

Btw, I haven't given up updating my bios. I will try the method suggested by
Multicom, which requires Windows 98 (!)
