hi, list
I've upgraded my kernel from 2.6.22.9 to 2.6.23 when it was out, After that
I can't install ELDK 4.1 anymore (The one I installed was crashed), it always
stopped at preparing install package XXX (or YYY sometimes), I've waited for
a very long time(more than 1 hour), but it still the same. After I switch
back to kernel 2.6.22.9, everything is fine. Is there somebody have the some
problem like me?
I've tried on two machines:
1. AMD DURON 1.6G, 512M RAM, gentoo 2007.0
2. INTEL Pentium 3 667M, 192M RAM, gentoo 2007.0
Regards,
Wang

What's your XXX or YYY?
What error messages did you get?
Why don't you try to update your glibc or something like that?
I am afraid it's off-topic here.

Not necessarily so if kernel version indeed makes the difference between
hung install and successful completion.
Perhaps he has any tasks stuck in 'D' state? If so, SysRq-t output for
these would be a good thing to collect. What leads him to suspect the
process scheduler, etc. More details are needed.
(I went looking for this package, but there are several, and they're
huge)

No error message, but the installation just "freeze", I've waited for more
than 1 hour, but still no progress, with 2.6.22.9 it was fine.

glibc is 2.6.1

The task is S+ state, please see in the attachment tarball, SysRq-t output has
also been attached, I wish it would help. I doubt it's the CFS problem
because it's first introduced into the 2.6.23 kernel.

(yeah, but there were a truckload of other changes as well)
Looking at your data, _my_ first suspect would be the 2.6.22->2.6.23
futex changes. I'd revert all of the changes to kernel/futex.c and
kernel/futex_compat.c, and see if the problem went away. If it didn't,
I'd then do a full git bisect to nail it down.

Thanks very much, also my glibc (2.6.1) is built under 2.6.23 (but not
linux-headers, which is 2.6.22). but I've tried right now (install ELDK4.1)
on another x86_64 machine, without any problem (x86_64, Core2Duo E6600, 4G
RAM)
