That was the output from a generic kernel. My debug kernel :was crashing the machine. 8-) I'm using flags 0xC0 for the debug :kernel. : :__ :Justin Bruce's patch didn't hurt, but it didn't help my -Os crashes either. I have to fallback to -O kernels, which sucks. I have no clue where the problem is. I am able to turn DDB and INVARIANT* on again. I haven't tried remote GDB debugging. -Matt Matthew Dillon [EMAIL PROTECTED] To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
Remote GDB *still* buggy...
I still can't get remote GDB to work correctly in a 5.0-current environment at speeds greater than 9600bps. Is anyone else experiencing similar results? I thought that grog had fixed this... -- Justin To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message

In GDB, you see some message about "malformed messages" and you can't seem to do anything. The other odd part is that speeds up to even 115200 work just fine up until the point that interrupt services are enabled. Then your hosed. -- Justin To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message

Hmm. In GDB, you see some message about "malformed messages" and you can't seem to do anything. The other odd part is that speeds up to even 115200 work just fine up until the point that interrupt services are enabled. Then your hosed. That's pretty much the symptoms I had been seeing until the fix. I don't understand why you're still seeing them; they were gone in a flash on my system. Are you sure you're using this revision? /* $FreeBSD: src/sys/i386/i386/i386-gdbstub.c,v 1.15 2000/05/18 02:29:23 grog Exp $ */ If so, try changing the two spltty()s to splhigh() and see if that makes the problem go away.
