Don't do that. 2) The easiest way to override the permissions and ownerships enforced during a make world is to use CVS to update your sources so that your local hacks to src/etc/mtree/BSD.*.dist are not overwritten on update. There are other ways, but the bottom line is that you should find a way to ensure that those files are modified to your taste before every world update. Ciao, Sheldon.

The problem with a hard lock-up out of which you can't escape into the debugger is that it makes meaningful bug reports impossible. My non-SMP workstation has exhibited apparently arbitrary lock-ups since the advent of SMPng. When I get a hard lock like this I usually try to see if I can reproduce it in single user mode. If I can, then I compile KTR into my kernel with the following options: KTR, KTR_EXTEND, KTR_COMPILE="0x3fff", KTR_MASK="(KTR_INTR|KTR_PROC)". Then I boot into single user (so I don't dirty filesystems), mount any needed fs's as read only if possible, and run the following command: # sysctl -w debug.ktr_verbose=1 ; command_that_makes_my_machine_go_boom And then stare at the tracing output on teh screen to see what the machine was doing when it hung. I.e., to see if it is still getting interrupts, and to see what process it died in, etc. From my understanding, John's WITNESS code allows us to break into the debugger from within interrupt context. If the lock-ups are happening in there, then this may help us provide better bug reports. Err, not quite. It's BSD/OS's WITNESS code, and what the WITNESS code does is perform extra checks on mutex enter's and exit's to ensure that we aren't handling mutexes in such a way that a deadlock is possible. Thus, it verifies that you don't grab mutexes out of order, or that you don't grab sleep mutexes with interrupts disabled, etc. -- John Baldwin [EMAIL PROTECTED] -- http://www.FreeBSD.org/~jhb/ PGP Key: http://www.baldwin.cx/~john/pgpkey.asc "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
