In my earlier (separate) post i was cautiously excited that the damn thing is not hanging anymore. Oh well, last night "it did it again" twice within 15 minutes. this time i got different errors then those i posted (here) earlier. I don't have the exact err message "handy", but i was "familiar" with it from my Centos5.5 times. IT was -110 and 64 - usb died and cant' recover, dead read blah blah. Google suggested to add "irqpoll" to grub. That didn't help at all. to T&M Unfortunately i can't confirm your theory as for rising temperature - it fluctuates around 40 - to 55C and doesn't seem to be corresponded to usbmadness.. Next steps : well, i'll try to play with acpi and irgpoll parameters and see if i can get it working this way.... //Mood: Frustrated
