Hi, I use vanilla kernels with realtime-preempt patches on a Core 2 E6600 running 32-bit Linux. Kernels up to 2.6.22.1-rt9 work fine, but I'm experiencing strange freezing of some tasks with 2.6.23.8-rt11. (Actually all 2.6.23 rt-kernels I've so far tried hang the same way.) The system boots up nicely and seems to be running properly, until something tips it off and some commands begin to get "jammed". What seems to trigger it is accessing the hard disk, for instance doing something like `grep -r foo /var`. When it happens the desktop seems mostly responsive, but trying to run commands like `ls` will freeze the terminal. Other commands will succeed, for instance `ps aux` works as usual. Alt-SysRq-w shows more than one blocked pdflush task, as well as metalog and whatever commands have become "jammed" so far, like `ls`. I'll be happy to post more information, I just need to know what. I'd attach my .config here, but I can't access the computer from where I'm at the moment.
