| |
This has been happening to me since ~9/25/2003, with the linuxppc-2.5 bk tree on an iBook. Have not seen this error on my Via mini-ITX system, which runs mainline BK, and also has OHCI 1394.
Problem: OHCI 1394 puts this error in logs. Happens if compiled-in or built as module.
Normally i see this once during boot, and the device(s) runs fine. Discovered i can make it happen at will with modular driver by plugging/unplugging devices, so i finally have a copy of the error message to send :)
Distro: Debian unstable Hardware: Mac iBook Devices: two Firewire disk drives (Cypress chipset, afaik)
