Subject: Using DiskOnChip on Intel IXP420
Date: Sun, 12 Feb 2006 17:55:24 +0100 [thread overview]
Message-ID: <43EF687C.9000107@repvik.org> (raw)
Hi,
I'm trying to get a DiskOnChip Plus to work with an Intel IXP420 arm
CPU. In the original kernel (2.4.22-uc0), it probed 0x50000000 for the
DoC chip, and found it. When I try probing using 2.6.15 or
2.6.16-rc2-git8, all I get is a kernel panic (below). I've tried using
both the old and new drivers, and I've tried using the latest CVS.
If anyone has any helpful tips or clues, I'd be very grateful.
