Jeez we have been sending folks into space for a long time now. Seems reasonable to me that a Murphy proof cockpit pressurization/O2 system is within reach?
Something weird is happening if they haven't been able to figure out the issue. It should not be that hard to debug the hardware, which makes me wonder about the software.
After all, we all remember back about 5 years ago, or maybe 6 years ago, when a group of F-22s flew across the date line and started having computer failures. I really wonder about the software. From what's been said publicly, they've looked at the whole system, top to bottom, looking for ways fumes could be introduced or oxygen restricted.
I'm surprised at how many times F-22s have been grounded for this issue over the past year.

Anything I say would be pure speculation — I have no systems knowledge of the F-22, but the fact that “software” is involved in what used to be a relatively simple O2 system tells me that some smart engineer tried to develop an “improved” O2 system and that it was fielded before being fully tested.
HST, I am back to my original statement — cockpit pressurization/OS systems have been around for a long time, and, most of them work pretty well. The more complex a system is, the more likely that there will be multiple failures, and the more likely it will be very expensive to maintain.
The KISS principle ought to be more widely followed, IMHO.
