Here is my diff config 3,4c3,4 < # Linux kernel version: 2.6.9-rc3-mm3-VP-T3 < # Sat Oct 23 21:30:53 2004 --- > # Linux kernel version: 2.6.9-rc3-mm3-VP-T3-lsm > # Sat Oct 30 19:54:32 2004 2082c2082 < CONFIG_SECURITY_CAPABILITIES=y --- > # CONFIG_SECURITY_CAPABILITIES is not set 2084a2085 > CONFIG_SECURITY_REALTIME=y I patched the source by hand, as patch using the diff Lee provided at http://lkml.org/lkml/diff/2004/10/8/243/1 complains of an incomplete patch Could the disks filesystem have some security setting that the kernel does not now have, post-patch? e.g. SECURITY_REALTIME=1 in include/linux/sysctl.h? Only a guess... Thanks for the help! I hope this enables my jackd to run in realtime without weird errors. -thewade
