I've a feeling my problems lie with the new disk driver setup, using pata/scsi .

It is a kernel panic, with a display of register contents, etc. Unfortunately this flashes by too fast to take down. > Look here for the latest drivers and relatived problems. I do have the latest orinoco_usb program, downloaded by svn co https://svn.sourceforge.net/svnroot/orinoco/branches/usb > The orinoco linux driver (generally and wifi) have a nice documentation > here : > > http://www.nongnu.org/orinoco/documentation/ Thanks for the pointer. I hadn't seen that. Unfortunately, though, the author of the orinoco_usb comments says that he ceased to run orinoco_usb in December 2006. The version of orinoco_usb in use then (which I was using) ceased to work with kernels later than 2.6.19 - and these older kernels ceased to work, on this machine at least, with Fedora-7. The orinoco_usb source is somewhat separate from the main orinoco_cs source, and is not included with the kernel sources. It is very much a one-man operation by Pavel Roskin, I think. >> So I am trying to compile a vanilla 2.6.21 kernel. >> This actually seems to run OK, >> but it waits for an extraordinary time >> when it enters the Interactive phase. >> What exactly is going on at that time? >> >> > What do you explan for interactive phase ?? When the computer says: Welcome to Fedora Press 'I' to enter interactive startup As I said, there is a very long (possibly infinitely long) pause at this point - I think I woke the machine by typing 'I' followed by more or less random characters. But what exactly is the kernel doing at this point? -- Timothy Murphy e-mail (<80k only): tim /at/ birdsnest.maths.tcd.ie tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland
