Hi Alan,
please find attached the results of some tests I did for
Linux-2.0.34pre14
on six different systems. I have included some information about
hardware-
and software-configuration, and also the tests I did.
Most of these tests I did for the past 2.0.34 pre-releases, too, but
I didn't have the time to write down a report like this (I couldn't
hardly set-up all those machines with the newest kernels, you were
just too fast releasing them... :-)
I hope this report is useful. If you need any more information feel
free to contact me.

Tests: =====
A) iX-SSBA benchmark suite A collection of various benchmarks (dhrystone, whetstone, linpack, byte, bonnie and others). Tests different aspects of system per- formance (hardware & software)
B) hbench A small program written by me. It requests a HTML page from a HTTP server as often as it can, using simple TCP socket I/O I usually let several hbench processes run on different clients, requesting pages from the same server
C) iozone Well-known file-I/O benchmark I usually let 3-5 iozone processes run on the same file-system, with the largest file possible (max. 2047 MB)
D) "find / -type f -exec md5sum {} \;" This is a simple stress-test for File-I/O and process creation
E) "find /net/hostname -print | cpio -ovB > /dev/null" Using the amd automounter, "/net/hostname" is a NFS-mounted filesystem. So this test checks network I/O and the NFS filesystem
F) "make dep; make clean; make zImage; make modules" Well known commands for Linux kernel-compilation
G) Standard programs emacs, netscape, top, qps, running at the same time
Test results for Linux-2.0.34pre14: ==================================
1.) Standard-Tests A) No problems on all systems
B) When running through system 2 (using IP Masquerading facility), these tests create "ip_masq_new(proto=TCP): no free ports." errors, as system 2 is running out of TCP masquerading ports. I don't think this is related to 2.0.34pre14 as there were no changes to that part of the kernel, but I haven't run this test on any kernel < 2.0.34prexy
C) No problems on all systems
D) No problems on all systems
E) some NFS-related errors ("nfs_rpc_verify: RPC call failed: 5") I got these messages on kernels < 2.0.34prexy, too, and they don't hurt very much.
F) No problems on all systems
G) No problems on all systems
2.) ISDN-related "oops"? On system 1 I got several "oopses" in icmp_send, which seem to be ISDN related. I already reported these yesterday.
3.) SCSI-driver lockup On system 6 I seem to have some problems with the internal SCSI controller. I'm using a slightliy modified Tekram DC-390T driver (for AMD 53C974 chipset) which sometimes(!) completely locks the machine. With Linux-2.0.33 it works fine, though.
Summary =======
2.0.34pre14 looks quite good. It seems to be very stable, even under high load: When I was running tests A-G simultanously on systems 3 and 4, system-load went up to 15, but I could still use emacs to read news and log-files without problems.
Most systems are up for more than 1 day now and still running without problems.
Test-result 2 seems to need some investigation (who is responsible for the ISDN dirvers in the 2.0.34 pre-releases?)
Test-result 3 is a special case: I patched the Tekram driver myself to get SCSI support for this notebook. With 2.0.34 these patches seem to be broken. I know there are new drivers for the Tekram controller with general AMD 53C974 support which make my patch obsolete, but I didn't have the time to try them out.
