 |
|
Hi I hope someone recognises my problem:
Ever since kernel 2.6.2 hit the streets, I've been having some problems with the firewire support of the kernel.
I have an iPod I connect through firewire to my computer running love-sources, but ever since 2.6.2-love1 hit the streets, ive been having problems. Heres some info from my 2.6.3-rc1-love1 kernel (same since 2.6.2-love1):
| Code: | ieee1394: Node added: ID:BUS[0-00:1023] GUID[000a27000215b416]

Whenever I try to modprobe sbp2 to activate the iPod disk, the modprobe command just hangs and the following is entered into my logfile:
| Code: | | sbp2: $Rev: 1096 $ Ben Collins <bcollins@debian.org> |
Which seems normal to me. The modprobe command hangs, but the machine is still working on all other fronts.
The ieee1394 part is compiled into the kernel and sbp2 is compiled as a module to be able to eject the iPod.
I've tried enabling and disabling kernel preemption, but to no avail, I don't have APIC enabled at this moment.
To be more complete, a my full .config can be found here and my dmesg output here.
Due to lack of time I have been unable to try out a vanilla 2.6.2+ kernel but the love sources patches don't seem to touch the firewire support of the kernel.
I hope to have provided enough info, any more info needed will be gladly provided.

| All I can do is confirm this behavior. USB mass storage devices also seems broken for me (nothing at all in dmesg when I plug it in...). I thought they have been testing these things.. Wasn't the entire 2.5 series enough time to get these things right? If I go back to 2.4, then the nvidia drivers mess up the console. If I stay at 2.6, then I can't do anything with my fancy peripherals.. |

I can confirm the same behavior with 2.6.2-mm1
results in a hang.
Nothing registers in the system log when I plug in the iPod. Was working fine with 2.6.1-mm5

oh well
the same behavour on other systems with the same kernel is good enough for me, I'll fall back to an older working kernel for now
