Re: pxa2xx_udc IRQ LOCK

OK, getting closer. pxa2xx_udc seems to be working with your config:

pxa2xx_udc: version 14-Dec-2003
usb0: Ethernet Gadget, version: St Patrick's Day 2004
usb0: using pxa2xx_udc, OUT ep2out-bulk IN ep1in-bulk
usb0: MAC 1a:60:19:07:1a:f0
pxafb_disable_controller: Disabling LCD controller
udc: USB reset
NET: Registered protocol family 2
<more pxafb related stuff>
IP: routing cache hash table of 512 buckets, 4Kbytes
TCP: Hash tables configured (established 4096 bind 8192)
NET: Registered protocol family 1
NET: Registered protocol family 17
NET: Registered protocol family 15
RAMDISK: Compressed image found at block 0
udc: USB reset
udc: USB reset
usb0: full speed config #1: Ethernet Gadget, using CDC Ethernet Subset

My PC now detects interface usb0. I (actually, my hotplug scripts) can ifconfig it without
any problems. linuxrc on the ipaq seems to have trouble though bringing up its interface.
I can't ping the ipaq for approx. 30 seconds. After that, ping works but I get a

spurious IRQ for DMA channel 5

(that's IRQ_PMU?) Then after some seconds tons of oopses follow (see the first one below).
Could this be related to my PC's USB 2.0 Controller?

Thanks,
Michael
