Hi, I'm having trouble with ehci on a 440epx based board, Things seems to go wrong after a reset of ehci controller. The board is running Linux 2.6.22, version tagged DENX-v2.6.22 from Denx git (git://www.denx.de/git/linux-2.6-denx.git).
The problem can be reproduced on the AMCC Sequoia board, compiling ehci and ohci as modules, along with usb debug messages. Inserting, removing and inserting back the ehci-hcd module triggers the error (See below for the full dmesg) : ppc-soc-ehci ppc-soc-ehci.0: reset command 01000b (park)=0 ithresh=1 period=256 Reset RUN ppc-soc-ehci ppc-soc-ehci.0: startup error -110 Those reset errors also happen when plugging some cheap usb keys. So far, i've tried to set park=3 and log2_irq_thresh=3 as these are the powerup values on the 440epx, but it doesn't make any differences. Any ideas about this ? Benoît Monin.
