*** Bug 219309 has been marked as a duplicate of this bug. *** Karsten, any chance of you getting me remote access to a machine with the b44 chipset plus one other working NIC? If you can't get another NIC then serial console access would be OK too. Thanks. Sorry, Herbert, but that's my own Dell 9400 Laptop with lots of private data on it. I can't give you access, but if there's anything I can test, I'll give it a try. I may be able to setup remote access on this machine for you when I return to North Carolina this weekend. I'm in TX right now, using a shared dynamic IP address. Would you be connecting from a Red Hat facility (i.e. Red Hat HQ in Raleigh)? I'll need some assurance that your side of the connection is reasonably secure. If so, I can temporarily open a ssh port on my firewall - login/passwd to be given verbally over the phone. Since I can't get any networking going while running the Xen kernel, you will only be able to work on the system while running the baremetal kernel. This is a Dell Inspiron E1705 (same exact computer as the 9400 - just branded for consumer market) In the meantime, would you like some "sysreports"? I've generated two, one each for xen and non-xen kernels. Commands used: Non-Xen: sysreport -dmidecode Xen: sysreport -norpm -dmidecode ## I figured you'd only need the rpm info once. Thanks Calvin. I work remotely so I won't be coming from a Red Hat address. Although I do use a static IP at home so I can give that to you for firewalling purposes. As to the actual machine, I do need to have Xen running on it so if you could setup a serial console for it then it would work. Otherwise what I need is more information about where exactly the first failure is. So first of all what does ifconfig show after has started? If the interface shows as up, then we'll need to sprinkle some printks in the transmit/receive routines. Otherwise we need to debug the b44_open function. Thanks. I'll probably be working late today at a customer site getting information for a Red Hat Support ticket on the NFS/kernel spinlock bug. My home office computer lab is where I'll be setting up your connection, so it'll be late tonight before it's done. I'm thinking I'll setup a SSH account on my DMZ machine and configure minicom to connect to the laptop's console port. That way you can stay connected during reboots and get the early boot messages as they occur. After reading a short bio on you I'm confident you will take all necessary precautions on your end. I would prefer to keep my IP address private so I'll send it to your email address. Thank you very much for your time!! Created attachment 144073 [details]
[LINUX] dma: Use swiotlb mask for coherent mappings too
Thanks to Calvin I'ved tracked down the issue to the fact that coherent DMA
mappings are still 31 bits wide rather than 30 which we've changed for
streaming mappings.
This is the patch that I submitted upstream.
Juan, when you get a chance could you please add the above patch to FC6? Thanks. Just updated to kernel-xen-2.6.18-1.2869.fc6, but I'm still getting errors from the b44 module: dmesg: --------------------------------------------------------- b44.c:v1.01 (Jun 16, 2006) ACPI: PCI Interrupt 0000:03:00.0[A] -> GSI 17 (level, low) -> IRQ 17 b44 0000:03:00.0: No usable DMA configuration, aborting. ACPI: PCI interrupt for device 0000:03:00.0 disabled b44: probe of 0000:03:00.0 failed with error -5 --------------------------------------------------------- Herbert, I can make my laptop available for testing again if needed. Please let me know ahead of time. Thanks! --Cal Sorry Cal, the fix just hasn't made it into FC6 yet. Hopefully it will soon. I have noticed that the fix was included on FC6 since release 1.2941. Could you check if the problem is fixed for you, on kernel 2.6.20-1.2941 or later? Sorry for the long delay without any reply on this bug. Yes, it started working about 2 updates ago for me. Thanks! |
