well, I could simply hang the machine when rmmoding the ohci driver in 2.4.20-ben10 ... so would consider testing rmmoding/insmodding for some time before accepting it... > > Jul 9 15:08:52 no kernel: ieee1394: unsolicited response packet received - > > np > > Jul 9 15:08:52 no kernel: ieee1394: contents: ffc09d20 ffc10000 00000000 > > 0e945194 > > Jul 9 15:09:52 no kernel: ieee1394: unsolicited response packet received - > > np > > Jul 9 15:09:52 no kernel: ieee1394: contents: ffc02520 ffc10000 00000000 > > db025194 > > ...

That is nasty and is not dealt properly by yes there was no error msg after that except when I wanted to eject the disc that I got Jul 9 11:39:51 no kernel: sr0: CDROM not ready. Make sure there is a disc in the drive. Jul 9 11:39:51 no kernel: sr0: CDROM not ready. Make sure there is a disc in the drive. Jul 9 11:40:04 no kernel: sr0: CDROM not ready.

So is all I can do sit and wait or would it help to supply some infos from what I get in xmon ? btw, I see my logs getting filled when using ifplugd and when I am on airport only with: Jul 6 18:20:12 no kernel: eth0: switching to forced 100bt Jul 6 18:20:19 no kernel: eth0: switching to forced 10bt I simply removed the offending lines from the kernel then it stopped... could this patch be included in your tree ? Soeren.
