Hello!
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: <NEC uPD 720100 USB 2.0 controller> on ehci0
usb4: USB revision 2.0
uhub4: <NEC EHCI root hub, class 9/0, rev 2.00/1.00, addr 1> 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?
