** Description changed: USB unstability on AMD 790FX chipset - Hello fellow users, + Hello, I'm having rather serious USB issues - while running Ubuntu 8.04 - and - hope to find either a solution OR confirmation that my mainboard is - dodgy in the USB department. + hope to find either a solution OR confirmation that the mainboard + (stated below) is dodgy in the USB department. When performing read/write operations on any type of cardreader or USB harddrive; the USB subsystem comes to a near-complete standstill - - everything freezes except for a secondary wireless keyboard - which - continues to work.. Badly.. + everything freezes except for a secondary wireless keyboard/trackball + combo - which continues to work.. But very badly after the error.. + (mouse cursor mapping hardly works). Without the ability to use USB + storage devices - this hardware / software combination is pretty much + useless to me. Only a full reboot returns the system to normal - zapping X doesn't help. Rebooting causes the system to repeat long system alarm beeps; right around the shutting down hal-daemon message. - Provided no mass storage devices are attached, the system works - perfectly. + Provided no mass storage devices are attached, Ubuntu works perfectly. I've tried "noapic" "nolapic" and "irqpoll" kernel options - but none of them have any influence. - I considered power problems; attached devices with powered hubs, - directly to the system ports (hardware side) - and also tried switching - from powernowd, to powersaved, cpufreq and dyncpu (software side) - but - the problem remains. + I considered power problems; attached devices with powered hubs as well + as directly to the system ports. - Frustrated with this problem - I even did the unthinkable.. and - installed Windows XP for a test run - ...and it works fine... + I also tried switching power management from powernowd, to powersaved, + cpufreq and dyncpu (software side) - but the problem remains. - Switching to Windows however will never be an option - I've been running - Linux since 1993 / 1994 and love it. + Frustrated with this problem - I even installed Windows XP for a test + run (for the first time in Years)- ...and it has no USB problems + whatsoever... + + Switching back to Windows or another Linux distribution is not an + option; + + A: I've been running Linux since 1993 / 1994 and love it. + B: Only Ubuntu features a completely free LTS option, and + offers commercial support for companies.

(The Debian project does not offer large scale + support for businesses... and openSolaris lacks too many + features at the moment). I've also tested the system on openSuSE 11.1 - which also works perfectly - aside from the occasional "ghost key strokes". ------could it be that Windows and SuSE up the voltage on the USB subsystem by default? or that they have a different device enumeration method? The system also won't boot any Debian or Gentoo based system from USB - which leads me to believe Debian and Gentoo may have similar configurations in USB handling. The hardware I use: PSU: Antec Earthwatts 650 Watt Mobo: MSI K9A2 Platinum (AMD 790FX chipset) CPU: AMD Phenom X4 9550 - GPU: Nvidia Geforce 8600GT - RAM: Kingston HyperX DDR-2 1066 running @ 800 Mhz for compatibility. + GPU: Gigabyte Nvidia Geforce 8600GT + RAM: 2 x 2 GB Kingston HyperX DDR-2 1066 running @ 800 Mhz for compatibility. Any thoughts? - Thanks in advance + Any comments on similar problems would also be helpful... + + Thanks in advance..
