Re: 5.2.1R panic on Sun Blade 100

2004-05-13 Thread Richard Cotrina 

The panic message :


IOMMU fault virtual address 0xc300
panic: pcib: uncorrectable DMA error AFAR 0xad6000 AFSR 0x21ff
syncing disk, buffers remaining ...
===

The nmap was a simple stealth scan with os fingerprinting :

nmap -sS -O 

The same error ocurred using ping with a big icmp packet (10,000 bytes).
In this case the panic message was :


IOMMU fault virtual address 0xc300
panic: pcib: uncorrectable DMA error AFAR 0xad6000 AFSR 0x41ff0080
syncing disk, buffers remaining ...

I cannot reproduce this problem on my machine; can you please post the
exact arguments to nmap that you have used, and the full panic
message?

5.2.1R panic on Sun Blade 100

2004-05-13 Thread Richard Cotrina 
Hello :

My Sun Blade 100 has experienced a "fault virtual address" panic, produced
by a simple remote port scanning (done with nmap 3.5). Searching the lists,
I've found a similar problem :

http://lists.freebsd.org/pipermail/freebsd-sparc64/2003-August/000576.html

according to this, the problem was caused by a lack of network card (dc)
support . My Sun Blade has an ERI Interface, which driver, gem,  uses the
pci bus too.

Anyone is having problems with Sun Blade and 5.2.1?

I am running the last 5.2.1R code from cvs. Here is my dmesg output :
