There obviously isn't one on UML, so if we're > looking at the same bug, it's in the generic code. The box has as AIC-7880U controller. OTOH, my dual P5 also has an AIC7xxx controller and I've never seen the problem there... On our quad Xeon this problem really seems to be phase-of-moon related; it hasn't shown up in the last 5 days or so under heavy stress testing, but when the kernel is compiled just a little bit different it doesn't happen. ;) regards, Rik -- Virtual memory is like a game you can't win; However, without VM there's truly nothing to lose... http://www.surriel.com/ http://distro.conectiva.com/ Send all your spam to aardvark@nl.linux.org (spam digging piggy) -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
