Re: [Linux-usb-users] Problem, irq 23: nobody cared (try booting with the irqpoll option)

Or it might have a handler registered for a different IRQ number, a wrong one. Sure enough. My firewire-free kernel worked fine all yesterday, but after leaving the laptop suspended overnight, the USB mouse failed, and dmesg says: hub 1-0:1.0: suspend error -16 suspend_device(): usb_suspend+0x0/0x20() returns -16 Could not suspend device usb1: error -16 PM: Writing back config space on device :02:00.0 at offset f (was 50a0100, writing 50a0109) PM: Writing back config space on device :02:00.0 at offset 6 (was 0, writing 1480) PM: Writing back config space on device :02:00.0 at offset 5 (was 0, writing 1400) PM: Writing back config space on device :02:00.0 at offset 4 (was 1, writing 1401) PM: Writing back config space on device :02:00.0 at offset 3 (was 0, writing 4000) PM: Writing back config space on device :02:00.0 at offset 1 (was 210, writing 217) and although I'm not getting any nobody cared messages, the behavior is the same (flaky mouse, and unplugging/replugging doesn't help). Any tips on finding the source of the extra IRQ9? Or on what option might have changed since about 2.6.19 to make the kernel more sensitive to the problem? ...Akkana - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

[Linux-usb-users] New device: Genesys Logic Webcam
Hello list, I just bought a new laptop based on the Santa Rosa platform (it's a rebranded Asus Z37E) and it contains a 2MP Webcam about which I can't seem to find any detail on the internet. I assume it's quite a new device so I think that this list is the best place to report it. The chipset included in the webcam is this one: http://www.genesyslogic.com/econtents/product02.asp?minicidx=11lastcidx=37SN=91 and the information offered by lsusb is this one: Bus 002 Device 003: ID 05e3:0503 Genesys Logic, Inc.

This started happening in 2.6.21 suddenly, which is why I tried upgrading to 2.6.22. Alan Stern writes: It would be a good idea for you to post this on the Bluetooth development list I don't think it's bluetooth specific. I just started seeing this too, and I don't have bluetooth. I built 2.6.22.1 and tried it; it worked for a short time, but then sound and a USB mouse (plugged in through an external USB2 hub) both started getting flaky. Turns out sound and USB are both on IRQ 9 (as is pcmcia, and I guess the pcmcia network card wins). The machine is a Vaio SR17 laptop. Strangely, 2.6.21.3 had been working fine for weeks, even with a hub. I got a dmesg similar to the one that started this thread (pasted at the end of this message). Booting with irqpoll does fix it, but I'd rather not do that: this is an old and slow PIII machine, but it worked great with older kernels. Booting with noapic doesn't help. Not long ago, I learned that IRQ 9 is commonly used by ACPI. I've got several machines which won't boot certain kernel versions (and this problem seems to come and go as the versions progress). Booting with acpi=off makes them all work. I have no idea why. You may also want to fiddle with any BIOS settings to enable/disable ACPI. Matt -- Matthew Dharm Home: [EMAIL PROTECTED] Maintainer, Linux USB Mass Storage Driver Although the OP was about IRQ 23, the above reply is about IRQ9. To contribute my own findings ( irq 7 ), which is now solved ( pci=msi,mmconf ) for an x86_64 kernel as mentioned in the end of the bug report below: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=244563 Regards, John - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
