We're running a DM365, with Montavista 2.6.18_pro500 kernel.
With a USB Flash drive, and a USB Connected DVD Drive, we're
experiencing kernel lockups
Having connected the JTAG, and stepping through the assembly, it would
appear that it is cycling through one of the two while loops in the
function channel_abort, in drivers/usb/musb/cppi_dma.c
Unfortunately its doing this with interrupts off!! and it never leaves!
Has anyone else experienced Kernel Lockups with USB devices connected ?
See if the following patch can fix it for you:
