Hi! Installed 2.6.0-test4 on my linux with Intel SHG2 motherboard, ServerWorks chipset (latest bios on date is 1.0.9 for this board). I have dual xeon configuration and pci LSI megaraid adapter .
Here's what i got working and not: Booting plain/clean 2.6.0-test4 don't gives me USB host controller working properly, lines from /var/log/dmesg regarging USB : SCSI subsystem initialized drivers/usb/core/usb.c: registered new driver usbfs drivers/usb/core/usb.c: registered new driver hub ACPI: Unable to set IRQ for PCI Interrupt Link [LN1] (likely buggy ACPI BIOS). Aborting ACPI-based IRQ routing. Try pci=noacpi or acpi=off ERROR: Unable to locate IOAPIC for IRQ -19/nACPI: Unable to set IRQ for PCI Interrupt Link [LN1] (likely buggy ACPI BIOS). Aborting ACPI-bas ed IRQ routing. Try pci=noacpi or acpi=off ERROR: Unable to locate IOAPIC for IRQ -19/nACPI: Unable to set IRQ for PCI Interrupt Link [LN1] (likely buggy ACPI BIOS). Aborting ACPI-bas ed IRQ routing. Try pci=noacpi or acpi=off ERROR: Unable to locate IOAPIC for IRQ -19/nACPI: Unable to set IRQ for PCI Interrupt Link [LN1] (likely buggy ACPI BIOS). Aborting ACPI-bas ed IRQ routing. Try pci=noacpi or acpi=off ERROR: Unable to locate IOAPIC for IRQ -19/n<7>IOAPIC[1]: Set PCI routing entry (3-4 -> 0xa9 -> IRQ 20 Mode:1 Active:1) 00:00:02[A] -> 3-4 -> IRQ 20 and the same booting 2.4.22 -> Aug 27 15:38:46 p4 kernel: usb.c: registered new driver usbdevfs Aug 27 15:38:46 p4 kernel: usb.c: registered new driver hub Aug 27 15:38:46 p4 kernel: usb-ohci.c: USB OHCI at membase 0xf89f6000, IRQ -19 Aug 27 15:38:46 p4 kernel: usb-ohci.c: usb-00:0f.2, ServerWorks OSB4/CSB5 OHCI USB Controller Aug 27 15:38:46 p4 kernel: usb.c: new USB bus registered, assigned bus number 1 Aug 27 15:38:46 p4 kernel: usb-ohci.c: request interrupt -19 failed Aug 27 15:38:46 p4 kernel: usb.c: USB bus 1 deregistered Aug 27 15:38:46 p4 kernel: Trying to vfree() nonexistent vm area (f89f6000) Aug 27 15:38:46 p4 kernel: usb.c: deregistering driver usbdevfs Aug 27 15:38:46 p4 kernel: hub.c: usb_hub_thread exiting Aug 27 15:38:46 p4 kernel: usb.c: deregistering driver hub You can see it's IRQ problem (-19). As a solution for 2.4.22 kernel i've used kernel option 'noapic' on command line to get my USB host controller working. For 2.6.0-test4 kernel, first i've tryed "pci=noacpi" - result was unable to load kernel at all, booting stopped at megaraid driver. The second try was "acpi=ht" in kernel parameters and linux has succesfully loaded. Trying to load ohci-hcd also has succeed. So i got my usb flash disk working. -- /mator ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-users
