Subject: can't print a mmaped region in gdb: Cannot access memory at address ...

Hi,

I'm trying to debug some code with gdb that mmaps() PCI address space
and mmaps a kernel GFP_DMA buffer. Outside of gdb mmap() interface is
working just fine, but when I try to print the mmaped memory from gdb
I get a 'Cannot access memory at address ...'

Is this a kernel ptrace() issue or a gdb issue? I'm using linux-mips
2.6.11 from 2005.03.18 on an Alchemy Au1550. Google didn't turn up
anything interesting on this subject.

                           Thanks,
                           Clem
