I'll just add a "me too" on this one. Closing as a duplicate. I'm obviously aware of the impact ofbut it's kinda hard to debug and it probably would simply go away with using ACPI for IRQ routing, so it's questionable whether it's really worth it In It's a SB chipset and therefore a duplicate of It's difficult to ati sb700 ohci usb controller whether or not it applies to the devices at hand or not as there's like absolutely no documentation for these bugs and therefore it's not so easy to judge what's going on at all.
If anyone with one of those super-broken SBx00 chipsets could apply and report back that'd be helpful. Link to documentation on the AMD southbridges from core boot.
NetBSD Problem Report #40056
The generic quirk of dropped interrupts seen in the BSDs might be at work here as well, causing more sporadic problems. Adding a keyword to not forget about that. Replying to stargatefan :. According to the errata it is broken and the Linux workaround the same as the NetBSD one this patch is ati sb700 ohci usb controller on is the way to go to work around it.
ITCH crashes when using scroll
Updated the patch with the additional info to use descriptive vendor, device, register and value names. Figured out my issue with the patch, got the patch applied and did a build. Kernel driver in use: k10temp. Subsystem: CardExpert Technology Device Update: Network configuration Code:. Hopefully this will go through to the Kernel and an ati sb700 ohci usb controller set of ISO images can be created.
Disabling the IRQ enabling code in the i irc service allows the system to boot into bdsh. October 17th, 3. What ati sb700 ohci usb controller i do? I also tried connecting a disk to the USB slot next to it there are two on each side but this seems to make no difference or makes it worse. It also has a card reader and if I put in an Sd card it seems to work better.
It sounds like an old record or something now with a bad needle. This can be the controller being programmed incorrectly by the driver and therefore not generating interrupts at all, the controller being broken and needing a workaround or the interrupt routing being broken and not actually routing the interrupt to the legacy PIC or not at the vector indicated by ati sb700 ohci usb controller BIOS.
Yes I know. That, and by extension the linux patches that are linked to, are the basis for the patch attached here. Some versions of these chipsets are simply broken AMD errata documents the issues and need such workarounds, however those are almost always edge cases.
In the case of the attached patch it'd require multiple devices being plugged in and heavily used to trigger that issue at all. So the early error in initialization seen by most people in this ticket and its duplicates most certainly are just an interrupt generation or routing issue, not a well hidden chipset bug. Can you try with hrev? There's a glimpse of hope that the Ati sb700 ohci usb controller just disabled PCI interrupts for the devices at hand which would now be changed on initialization and a corresponding line would be printed to debug output.
Computer Hope Forum
I see if in the eratta on page 26 of this document. Apprently there are a number of power states, they are not available in the ohci and according to the block diagrams the ehci must recieve a power state message to begin working.
I have a suspicion that this applys ati sb700 ohci usb controller most of the AMD chipsets and it could explain why the interupt request is being ignored. I find that highly unlikely and I wouldn't have seen anything in that direction in any of the controller driver sources of any other OS. I am changing the summary to reflect this fact.
