The key word in Ivan's phrase is "less mangled". Neither use of or increasing PRINTF_BUFR_SIZE solves the problem of interspersed console output. I've been ranting/raving about this problem for years now; it truly looks like a mutex lock issue (or lack of such lock), but I've been told numerous times that isn't the case. To developers: what incentives would help get this issue well-needed attention? This problem makes kernel debugging, panic analysis, and other console-oriented viewing basically impossible. -- | Jeremy Chadwick j...@parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
