I'm sorry you have been having trouble. You might consider posting to the misc@ mailing list, as it reaches a much wider audience than here, and the misc@ audience includes approximately half of the OS developers. This forum has a much smaller reach, though we are newbie focused and the misc@ mailing list is not. At all.
If you were to post this same information there, it is possible that someone will recognize your symptoms and recommend a solution. It is far more likely that your post will be ignored for being incomplete.
If you do get responses, these will invariably recommend -- with a range of civility betwen polite and very rudely -- that you post your dmesg, rather than excerpts. Without a complete dmesg, unless someone recognizes your particular issue, you won't get much help other than "try a recent snapshot". If you respond negatively there to requests for more information, no matter how rudely put, it is likely the only positive recommendations you will receive afterwards will be to please go use a different OS.
If instead of misc@, you submit your limited problem report to bugs@, any responses received are likely to be even ruder, if that is possible. Though someone may just reply off list with a link to
www.openbsd.org/report.html in an effort to help you restructure your report.
