Re: panic: Going nowhere without my init!

2009-01-19 Thread Kamlesh Patel
Hi All,

Sorry for late reply, i was out of work for a week.
I made wrong comment in Getpid():

Getpid() {

/* ..

/* ... */

 */

return()
}

I removed it and now it is working fine.

Thanks

 I guess if you break getpid() to not return 1 in the case of init(8), it
 will just say init: already running and quit. This causes this
panic
 to occur.

Who knows?  We have no idea what the OP actually did, because he didn't
bother to tell us.

Remote kernel debugging in FreeBSD using serial communication

2009-01-17 Thread Kamlesh Patel
Hi All,

I am trying remote kernel debugging in FreeBSD using serial communication. I 
got the following link.

http://www.ibm.com/developerworks/aix/library/au-debugfreebsd.html#list1

My problem is my developing and target system does not have DS25 female port.

Anyone have any idea about Remote kernel debugging in FreeBSD using DS9 F/F 
Serial cable or any other remote debugging idea?

Thanks,
Kamlesh

It's set by machine-dependent part of code. grep for
phys_avail[] in i386/amd64/arm/etc..
