Subject: [parisc-linux] BUG 2.6.12-rc3-pa1 PCI mmap panic
Date: Sun, 1 May 2005 01:49:01 -0600	[thread overview]
Message-ID: <20050501074901.GA13801@colo.lackof.org> (raw)

Trying to get "tvflash" running on pa8800. tvflash is a userspace
firmware flash tool for mellanox infiniband boards.
Works fine on x86, x86-64, ia64, ppc, and sparc64.
"tvflash -i" is supposed to go off and identify all
installed mellanox boards and which firmware rev they
currently have.

The panic is in pfn_to_nid():
        r = pfnnid_map[i];
        BUG_ON(r == 0xff);	<---- panic

Any clue what's broken?


[ sorry - feels like I'm reporting alot more problems than I'm
fixing lately *sigh* ]

thanks,
grant
