This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --------------enig3EB32881BAF294FE3AC74F5E Content-Type: text/plain; charset=UTF-8; format=flowed Content-Transfer-Encoding: quoted-printable Hi, I have a AMD Geode (embedded platform) based hardware with problems in=20 EHCI. Here's an excerpt from dmesg: ohci0: <OHCI (generic) USB controller> mem 0xe0215000-0xe0215fff irq 11=20 at device 15.4 on pci0 ohci0: [GIANT-LOCKED] ohci0: [ITHREAD] usb0: OHCI version 1.0, legacy support usb0: SMM does not respond, resetting usb0: <OHCI (generic) USB controller> on ohci0 usb0: USB revision 1.0 uhub0: <AMD OHCI root hub, class 9/0, rev 1.00/1.00, addr 1> on usb0 uhub0: 4 ports with 4 removable, self powered ehci0: <EHCI (generic) USB 2.0 controller> mem 0xe0216000-0xe0216fff irq = 11 at device 15.5 on pci0 ehci0: pre-2.0 USB rev device_attach: ehci0 attach returned 6 USB 1.0 works fine with cca 1 MB/s transfer rate from a flash memory=20 drive. EHCI capability works fine in Linux.

Any ideas on what should I try? --------------enig3EB32881BAF294FE3AC74F5E Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.5 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFHmRMdldnAQVacBcgRAtLZAKDNt3IMcUc/USCqoQO6+rOB9emqKgCfeKfG MDhxTyZHkglrKFd/L1AOdVQ= =MNwV -----END PGP SIGNATURE----- --------------enig3EB32881BAF294FE3AC74F5E--
