Message-ID: <20030310163401.GA21175@troypc.fc.hp.com> Mail-Followup-To: linux-kernel@vger.kernel.org Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.3.27i Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org I seem to have found a bug in 2.4.20. I am running on a dual processor PIII with a ServerWorks (RCC) chipset that has 3 32-bit 33MHz 5V PCI slots and two 64-bit 66 MHz PIC slots. Starting with 2.4.20 my Adaptec 39160 is no longer detected (it's in a 64-bit slot). I have tried both slots and every possible kernel config I can think of, including booting with pci=noacpi. The card does not show up with a lspci or cat /proc/pci. If I compile the AIC7xxx driver as a module and try to load it, I get a message that says that I do not have the device installed. 2.4.19 and below are fine. This patch from the rc3 -> rc4 changelog just caught my eye. Fixup pci_alloc_consistent with 64bit DMA masks on i386 I will try 2.4.20-rc3 tonight to see if I can nail it down to specific version. However, before I put to much effort into this, is this a known issue? I searched the archives and haven't seen anything related yet. Thanks, Troy
