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.

[Linux-usb-users] Comsol UHD-3542 3.5 HDD enclosure ( PATA to USB 2.0 )

So now the question is: *) Why does it work with full-speed if connected prior to startup, but works only with high-speed if connected after startup ?? It's quite possible that your BIOS is causing the problem. Check the USB settings in your BIOS configuration and see if changing them helps. Alan Stern Unfortunately, the Pheonix BIOS settings on my laptop does not have any advanced settings like you would on a desktop PC. I only have date/time setting and info about CPU, memory, boot options ( as in order of booting, etc.. ) and security settings, and hard disk diagnostics. Furthermore, if I boot from a vanilla 2.6.21-1 kernel without the USB enclosure attached, and then attach it after bootup, nothing even gets logged on /var/log/messages saying that it detected a usb device connected, but if I unplug and plug my USB mouse, it gets logged. I enabled full USB debugging, but nothing gets logged plugging and unplugging the USB enclosure. Anyway, what I have not tried is to boot with vanilla 2.6.21-1 with the USB enclosure already attached, to see if that helps ( like with using the FC6 kernel ).

[Linux-usb-users] Hard drive enclosures that work with linux-usb
Running with FC6 and kernel-2.6.20. I recently bought a Comsol UHD-3542 3.5 enclosure, and I could only get it to work with ohci and not ehci. There is not much in the list of what hard drive 3.5 PATA to USB 2.0 enclosures work, except this: http://www.qbik.ch/usb/devices/showdevcat.php?id=11 ... and there are only 2 enclosures in there, but only 2.5 ones. So am wondering what if any, 3.5 enclosures have one used successfully ( PATA to USB 2.0 with ehci ) ? - 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.
