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.
