Subject: [Xenomai-help] Ipipe causes PCI / USB crash
Date: Mon, 29 Sep 2008 15:29:01 -0400 [thread overview]
Message-ID: <48E12C7D.4050802@domain.hid> (raw)
I have a Sequoia (PPC440EPx) evaluation board, with an Agere USB interface
plugged into the PCI bus. The kernel is DENX 2.6.26.1 with Ipipe 2.2-04
from the xenomai-2.4.5 release.
If Ipipe is included in my .config, then when I plug in a Sandisk flash
device, I get the crash shown below. If I remove Ipipe from the .config,
then the flash device works correctly.
Please let me know if additional information is needed to help diagnose this.
Thanks,
Steve
