Hmm, since I havn't been able to get my hands on the problem (I've been running 3 systems here with tags all over since the first report, not a single hickup yet :( ) I can't tell whats going on, it might be that the drive somehow gets really confused I dont know, for now those having tags problems should just not enable it... > What's your theory on it? None so far, I've instrumented the code here, and I simply cannot see what should go wrong (yet). BUT recent current with the busdma'd ATA driver screws up with tags, fix is coming as soon as I get a few hours to commit it... -Søren To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
