Hello,
I am currently experiencing problems getting a 2.6.x system working on a
Radisys 6315 PMC Processor board. This board has a Raisys 82600 chip
interfacing to an EZ-USB device onboard.
The system has been tested with the following kernels :
OK - 2.4.17, 2.4.29
FAILS - 2.6.5, 2.6.9, 2.6.11, 2.6.11-bk6
The failure behavior is somewhat strange - there are two USB ports on each
card, and the fault *only* occurrs when only a single port is in use. On
the cards where two devices are connected, everything seems to work OK.
The fault occurs immediately after the "fxload" program is called to load
the hex file onto the EZ-USB device. This causes all of the devices to get
disconnected and re-enumerated, at which point a large number of spurious
uhci_hcd interrupts are generated (~150000 on average), and all of the
devices fail to accept their descriptors.
I am aware that this could easily be a hardware quirk/issue, but having
successfully used the hardware with 2.4.x, it is neccesary for me to find a
workaround that will allow the hardware to work with the new USB subsystem
in 2.6.x
Below I have attached kmsg output (verbose USB debugging enabled),
before/after proc/interrupts, and a lspci output.
If anyone could provide any suggestions, it would be much appreciated.
Regards,
Steve Hardy
