Hi,
I am trying to broadcast an NMI like this:
send_IPI_allbutself(NMI_VECTOR);
But when I do this, I get a divide error:

CPU: L2 cache: 128K
CPU1: Intel Pentium II (Klamath) stepping 03
checking TSC synchronization [CPU#0 - CPU#1]: passed.

Hi to all,
I made a simple driver in which llseek go trough

offset += file-f_pos;
break;

Hello,
I'm working on a 32-bit BIOS program for some embedded system with 64-bit
CPU and I'm trying to test 64-bit mode. The BIOS normally runs in 32-bit
mode. It, however, needs to performs some test for the 64-bit mode. So the
drill is to jump to Long mode, perform some test (for now, I just

The stack trace starts here:

Looking at this:
kernel/irq/spurious.c:int noirqdebug_setup(char *str)
Does Linux made the transition from 16bit at bootup to 64bit? Or
does it first go into 16bit-32bit-64bit?
I am not sure

mulyadi may be right..but anothere possibility was that the
stracing introduced delays which made all the problem go
away.ie, asynchronous operation between reader and
writer..which appear as missing interrupt (check internet for
this - many causes)
bottomline is why not introduce
