Recently I decided to move to 2.6.x kernel series and all is fine but USB support. The problem looks like this: - Without USB support linux boots fine. - With USB support linux stops booting at some time and computer is just frozen. Keyboard doesn't work. The only thing I can observe is that just during loading USB modules hard disk starts working louder until the manual power_off which is necessary because machine is dead at that time. All was fine with 2.4.x series. The problems started when I moved to 2.6.x. I tried all 2.6.x versions released until now. None of them works fine with my machine with USB support enabled. here is a little output from console during booting sequence: drivers/usb/core/usb.c: registered new driver hub ehci_hcd 0000:00:0c.2: EHCI Host Controller ehci_hcd 0000:00:0c.2: irq 11, pci mem df9e7800 ehci_hcd 0000:00:0c.2: new USB bus registered, assigned bus number 1 ehci_hcd 0000:00:0c.2: USB 2.0 enabled, EHCI 0.95, driver 2003-Jun-13 hub 1-0:1.0: USB hub found hub 1-0:1.0: 4 ports detected drivers/usb/host/uhci-hcd.c: USB Universal Host Controller Interface driver v2.1 uhci-hcd 0000:00:0c.0: UHCI Host Controller That's the last thing i can see. After this computer is dead. some more details: - Sony Vaio PCG-FR285M laptop - linux 2.6.0-test6-bk4 - no devices connected to USB ports during booting sequence - gcc 3.2.2 - module-init-tools-0.9.15-pre2 Any suggestions on this? If you need some more information please feel free to ask me. Best Regards, Mariusz Kozlowski
