I'm suffering from a fully reproducible panic, that strikes, when I connect a umass storage device (Blackberry Pearl with a mini-SD card inserted) to the EHCI USB port. The system runs a freshly rebuilt 7.3-stable/amd64. The crash is somewhere inside USB-stack. The stack, as produced by kgdb, can be found at: http://aldan.algebra.com/~mi/tmp/usb-crash.txt The usb4-process -- the current process at the panic-time -- is associated with: usb4: EHCI version 1.0 usb4: companion controllers, 3 ports each: usb2 usb3 usb4: on ehci0 usb4: USB revision 2.0 uhub4: on usb4 The system is running has 6Gb of RAM and 2 dual-core Opterons. The connection was just fine with 7.2-stable from March 5th, although that kernel was not an SMP one (by mistake). Please, advise. Thank you, -mi P.S. Is the USB supposed to work in 7.x, or do I have to go to 8.x for it to work reliably?
