Hello,


I downloaded 2.4.20 kernel from kernel.org, and patch
kdb-v3.0-2.4.10-common and kdb-v3.0-2.4.20-i386 into the kernel.
Then, I put this  kernel (compiled by gcc-.2.96)  to a SMP machine. set a
break point by using bp,
after the machine hit the break point, I use bt and cpu commands to check
the status. Then I type bc 0 to clear that break point, and go to trying
to leave kdb. But I never can go out, it always hit "Oops int3 ". I think
it is the problem only happen on SMP machine, because another UP (unit
processor) never has this problem.

Today, I try v4.0 and other two patches kdb-smphdr-v4.0, same problem
happened.

Doese someone has some solutions about this.

Thanks!
Hua
