Hi Kernel-Hackers ;) I have a ALI1394 Firewire (IEEE1394) card called PowerMagic. According to the ALI Homepage it is OHCI1394-compatible. It works fine with the standard windows 98SE OHCI1394 driver.
After solving the sound problems I tried again modprobing the ohci1394 driver with the current 2.4.17.5mdk kernel. Last time with kernel 2.4.16 driver I got a complete lock up, with the help of firewire developers I managed to get output errors before the crash happened. The same procedure now shows the following output: [root@linux]# lspci 00:00.0 Host bridge: Acer Laboratories Inc. [ALi] M1541 (rev 04) 00:01.0 PCI bridge: Acer Laboratories Inc. [ALi] M5243 (rev 04) ... 00:0c.0 FireWire (IEEE 1394): Acer Laboratories Inc. [ALi]: Unknown device 5251 (new lspcidrake: unknown : unknown (10b9/5251/ffff/ffff) [SERIAL_FIREWIRE]) ... [root@linux]# lspcidrake unknown : Acer Laboratories Inc. [ALi]|M1541 [BRIDGE_HOST] unknown : Acer Laboratories Inc. [ALi]|M5243 [BRIDGE_PCI] ... unknown : Acer Laboratories Inc. [ALi]|M5229 IDE [STORAGE_IDE] ... [root@linux]# echo 8 >/proc/sys/kernel/printk [root@linux]# tail -f /var/log/syslog& [root@linux]# modprobe ohci1394 The output in the log file looks like this: ohci1394: $Revision: 1.80 $ Ben Collins <[EMAIL PROTECTED]> PCI: Fount IRQ 5 for device 00:0c.0 PCI: Setting latency timer of device 00:0c.0 to 64 According to the linux1394-devel ML the CVS driver should work, I did not try it yet as I saw that there was a new version of the ohci1394 driver in the 2.4.17 kernel. An interesting side aspect: I had the DVB driver loaded in parellel and I still heard the sound of the tuned channel while the computer did not react to any of my keyboard inputs. (DVB driver: See http://www.linuxtv.org, not recommanded for the faint of heart, but works fine for me since months, I have created a new spec file today for the snapshot file of 20020116) The DVB driver has no influence on the 1394, as it hangs without DVB driver as well. The only other thing I could possibly do is to add output to every function in the driver which is called. Before I do that I'll try out the linux1394 cvs driver.
