Subject: Re: [announce] [patch] ultra-scalable O(1) SMP and UP scheduler
Date: Fri, 4 Jan 2002 08:42:37 +0100 [thread overview]
Message-ID: <20020104074233Z288526-13996+840@vger.kernel.org> (raw)
After the loop.c fix (nfs.o and sunrpc.o waiting) I got it running here, too.
2.4.17
sched-O1-2.4.17-A0.patch
00_nanosleep-5 (Andrea)
bootmem-2.4.17-pre6 (at all IBM)
elevator-fix (Andrew, worth it for 2.4.18)
plus ReiserFS fixes
linux-2.4.17rc2-KLMN+exp_trunc+3fixes.patch
corrupt_items_checks.diff
kmalloc_cleanup.diff
O-inode-attrs.patch
To much trouble during 10_vm-21 (VM taken from 2.4.17rc2aa2) merge. So I
skipped it this time. Much wanted for 2.4.18 (best I ever had).
All the above (with preempt and 10_vm-21 AA except sched-O1-2.4.17-A0.patch)
didn't crashed before.
One system crash during the first X start up (kdeinit).
ksymoops 2.4.3 on i686 2.4.17-O1. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.17-O1/ (default)

More processes die during second and third boot...
I have some more crash logs if needed.
Preempt plus lock-break is better for now.
latencytest0.42-png crash the system.
What next?
Maybe a combination of O(1) and preempt?
