Hi, i posted a bug about amd hanging at boot time a few week ago,
does anybody has a fix for it ?
The bug is described here :
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=90902
it seems that several groups of users besides me encounter the same
bug....
If not, i'll have to post-install a 2.4.18 kernel on all my new
RH9 boxes :-(

Looks like YAFP (Yet Another Futex Problem).
Have you tried running with LD_ASSUME_KERNEL=2.2.5 ?

You are right, setting LD_ASSUME_KERNEL=2.2.5 (or
LD_ASSUME_KERNEL=2.4.1) corrects the problem.
Do you have more info on this ´bug' ?

As a rule of thumb, whenever a program deadlocks in a futex call,
setting this variable to a < 2.5.x value might prevent the deadlock.
Google around for the exact reason why.
AFAIU, it's a RH 9.0 bug.
