Bug#411696: linux-2.6: r8169
Package: linux-2.6 Severity: important When attempting to install with d-i daily builds (or hand built d-i images) via the network I find that I am unable to use r8189 network controllers which had ethernet cables connected at modprobe time. The system detects the three r8169 controllers that are present and detects link state on them correctly (as reported in dmesg). ifconfig reports that an ethernet controller which had the cable connected at modprobe time has dropped a small number of transmitted packets and 0x (roughly) received packets with no successful traffic. Controllers not cabled at modprobe time appear to work with no ill effects. uname -r reports this as version 2.6.18-4-486. This appeared to work fine with 2.6.18-3-486. Severity important since this has a major effect on d-i usability. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]
Bug#415476: natsemi: Fix for interrupt sharing issue
Package: linux-image-2.6.18-4 Severity: important Tags: patch Kernel 2.6.18 contains a version of the natsemi driver which supports NAPI but has buggy handling of shared interrupts. The patch below (which is a slightly cut down version of one which has been accepted upstream, omitting reversion of another change which worked around this problem) fixes this. The active part of the patch is the very first chnage. Severity important since this can cause the driver to hang on machines where a natsemi device shares an interrupt. Subject: natsemi: Fix NAPI for interrupt sharing The interrupt status register for the natsemi chips is clear on read and was read unconditionally from both the interrupt and from the NAPI poll routine, meaning that if the interrupt service routine was called (for example, due to a shared interrupt) while a NAPI poll was scheduled interrupts could be missed. This patch fixes that by ensuring that the interrupt status register is only read by the interrupt handler when interrupts are enabled from the chip. Thanks to Sergei Shtylyov [EMAIL PROTECTED] for spotting the issue, Mark Huth [EMAIL PROTECTED] for a simpler method and Simon Blake [EMAIL PROTECTED] for testing resources.

Bug#618319: linux-image-2.6.37-2-amd64: Framebuffer issues with RV620
Package: linux-2.6 Version: 2.6.37-2 Severity: normal As soon as the kernel switches to framebuffer mode on 2.6.37-2-amd64 the display becomes unrecoverably corrupted though everything appears to continue to run fine and a reboot can be initiated.

(The existing snd-pcm-oss and snd-mixer-oss don't seem to be good enough.) Specifically since they are in kernel they don't (and can't really) play at all with any userspace ALSA stuff such as DSP, PulseAudio or the various network and wireless I/O drivers that are implemented in userspace. They also cause pain for the standard ALSA drivers since the mismatch between the OSS and ALSA configuration APIs results in ALSA drivers having to jump through hoops for the benefit of the OSS emulation, and the OSS configuration model is just too limited to express the control available on many modern systems. -- To UNSUBSCRIBE, email to debian-kernel-requ...@lists.debian.org with a subject of unsubscribe.

That's ASoC: fsl: Fix module build. imx-pcm-{dma,fiq}.o are exporting various symbols used by snd-soc-{fsl,imx}-ssi.o. Obviously, a module can use symbols exported from both built-in and modular code. And yet for some reason this didn't work when the exports were built-in and did work when they were built as modules.

Not really, the issue you're seeing is just a plain resource leak in the driver that happens to blow up worse than normal in your particular configuration. This isn't even something related to probe deferral at the regulator level, the core is complaining that your system description is buggy as it has omitted some of the supplies for the device (notice how it says "using dummy regulator"...). This is happening a lot as the DWC3 driver is leaking, it is happening at all because when the Exynos DWC3 integration creates it PHYs it doesn't map the supplies through to them (it should be registering a supply alias to do this). The patch you linked to was for a completely different error message which is at least related to probe deferral, though fundamentally unless we just stop printing diagnostics (which is getting more and more tempting to be honest) I'm not sure anything is going to fully resolve leaks like this, the best chance you've got is something that explicitly looks at the dependencies like Raphael was proposing. signature.asc Description: PGP signature

AFAICT the fact that every time the dwc3-exynos driver probes it creates a new child device which successfully instantiates means that we end up constantly running deferred probes. It should only create the child devices if it managed to get the other resources, that way we don't get the constant deferred probe retries. signature.asc Description: PGP signature

I dimly recall seeing some discussion of issues here in the past, though I don't have one of these boxes myself so wasn't paying huge attention. I'd guess there's some bug in the DT which given that this is in the firmware the kernel ought to fix up during early init, if someone with better access to one of these systems could supply a DT for inspection that might help people figure things out. I suspect the machines might work fine when booted with ACPI firmware.

Bug#993612: [PATCH] of/address: Return an error when no valid dma-ranges are found
Commit 7a8b64d17e35 ("of/address: use range parser for of_dma_get_range") converted the parsing of dma-range properties to use code shared with the PCI range parser. The intent was to introduce no functional changes however in the case where we fail to translate the first resource instead of returning -EINVAL the new code we return 0. Restore the previous behaviour by returning an error if we find no valid ranges, the original code only handled the first range but subsequently support for parsing all supplied ranges was added. This avoids confusing code using the parsed ranges which doesn't expect to successfully parse ranges but have only a list terminator returned, this fixes breakage with so far as I can tell all DMA for on SoC devices on the Socionext Synquacer platform which has a firmware supplied DT. A bisect identified the original conversion as triggering the issues there.

We'd need to add a similar check in the first loop. It should work otherwise though and avoids doing the allocation in this case. signature.asc Description: PGP signature
Bug#993612: [PATCH v2] of/address: Return an error when no valid dma-ranges are found
Commit 7a8b64d17e35 ("of/address: use range parser for of_dma_get_range") converted the parsing of dma-range properties to use code shared with the PCI range parser. The intent was to introduce no functional changes however in the case where we fail to translate the first resource instead of returning -EINVAL the new code we return 0. Restore the previous behaviour by returning an error if we find no valid ranges, the original code only handled the first range but subsequently support for parsing all supplied ranges was added. This avoids confusing code using the parsed ranges which doesn't expect to successfully parse ranges but have only a list terminator returned, this fixes breakage with so far as I can tell all DMA for on SoC devices on the Socionext Synquacer platform which has a firmware supplied DT. A bisect identified the original conversion as triggering the issues there.
