ISTR that an _old_ version of lilo was mentioned earlier in this thread. As a datapoint, on my one desktop box which uses lilo (an athlon64 uniprocessor) both 32 and 64-bit 2.6.25 kernels boot fine. Both of those systems are with lilo-22.8, and gcc-4.2.2.
But, I think you (Bart) haven't said which version of lilo you are using ? If it isn't recent, perhaps upgrading it might help ?
For Sergio, you have my sympathy. I totally failed to bisect my own problem with 2.6.25-rc (and 2.6.24.1), although I did find the problem by other means, and got a work-around, so I'm not competent to diagnose what is wrong, but maybe I can help to tease out what is different about your box. As a start, you could try diffing your config's for 2.6.24.5 and 2.6.25 in case something odd has changed.
Or, perhaps this is a problem specific to a certain processor ? So far, I think all the list knows is that you have a problem, and an old version of lilo. More data might eventually help to identify what is causing this. If you have a fairly old version of lilo, maybe you also have an old version of gcc ?
For Bart too, which version(s) of gcc are you using on the systems where lilo is slow to load, and which cpu(s) do you have there ?
Ken, who relies on lilo for his server, and gets worried by reports of trouble with it. -- das eine Mal als Tragödie, das andere Mal als Farce -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
