I see the same problem on an Asus A7V Athlon motherboard (VIA KT-133 chipset). I've regenerated the RedHat 7.3 installer CDs with the 2.4.20-18.7 errata kernel, I'm not able to install on that box since then. I'm doing a bootnet installation, here is what I get after the installer has tried to modify the partition table on /dev/hda: - on the primary console, I get the following error message: The kernel was unable to re-read the partition table on /tmp/hda (Device or resource busy). This means Linux knows nothing about any modifications you made. You should reboot your computer before doing anything with /tmp/hda. (Here you can only press 'Ignore' which is ignored, the error messages keeps appearing - on the Alt-F4 console, there is 10 times the line: i8253 count too high! resetting... I changed the kernel parameters in the syslinux.cfg of the bootnet floppy and added ide=nodma, but it did not change anything. Are there other boot options that could help this problem or will a kernel errata be the only workaround for this issue? TIA Greetz Marc I'm seeing the same message on an A7A-266, since I've upgraded to kernel-2.4.20-13.7. Never seen it before. The box has been kept up to date, and previous kernel versions, starting with 2.4.18-5 and up to 2.4.18-27.7.x (included) showed no problems. The uptime right now is 12 days, and the box showed no other problems, just annoying messages in syslog: i8253 count too high! resetting..

I seem to remember a similar message about a via timer bug back in 2.2 times but went away (dunno exact kernel versions tho) and it did not occur on 2.4.20 until 2.4.20 I am seeing this with RedHat 8, Kernel 2.4.20-19.9 on my laptop, a Toshiba Portege 4000. I don't know the maker of the motherboard. The system is running natively, not under vmware.... This machine does not get much use running linux, but I never saw this before running 2.4.20-19.9. And I never saw it under RH 8 on this machine. Overnight, with no one using the machine, isolated on my home lan, also with NO use at night, the condition occurred four times. The system did not lockup. A typo. That's Redhat 9, not 8. *** Bug 102973 has been marked as a duplicate of this bug. *** I've seen the same error as well, on a non-athlon system (HP dl380G2) I get this with severn on an HP Pavilion 4400 series (Athlon ATI / ALi) 00:00.0 Host bridge: ATI Technologies Inc: Unknown device cab0 (rev 13) 00:01.0 PCI bridge: ATI Technologies Inc PCI Bridge [IGP 320M] (rev 01) 00:02.0 USB Controller: ALi Corporation USB 1.1 Controller (rev 03) 00:06.0 Multimedia audio controller: ALi Corporation M5451 PCI AC-Link Controller Audio Device (rev 02) 00:07.0 ISA bridge: ALi Corporation M1533 PCI to ISA Bridge [Aladdin IV] 00:08.0 Modem: ALi Corporation Intel 537 [M5457 AC-Link Modem] 00:0a.0 CardBus bridge: O2 Micro, Inc.

I'm seeing this too. NFS server with Asus A7A266, Athlon 1400. After upgrading the kernel from 2.4.20 to 2.4.24 one of the NFS-clients (the busiest one, shell/mail-server) started hanging. I tried everything on the client but booting back to 2.4.20 on the server only helped. The hangs on the client seems to be correlated to these "i8253 count too high! resetting.." on the server. This was the first time I've seen load averages over a thousand! :) slackware (version kind of floating). This is happening on our HP BL20p G2 blades (Xeon 3.0GHz) running RHEL3 AS, kernel 2.4.21-9.0.1.ELsmp, the latest for this channel via RHN. I would like to know the nature and severity of this bug. Can a system with this problem be considered stable and reliable enough for a critial production server? If not, any word on when a RHEL3 AS kernel that fixes this might appear on RHN? I've found this thread, I think this is where the warning messages has been introduced into the kernel... http://www.ussg.iu.edu/hypermail/linux/kernel/0211.0/0330.html The patch should be this one: http://www.ussg.iu.edu/hypermail/linux/kernel/0211.0/1992.html As I read it, the warning is harmless, the kernel fixes the problem as soon as it's detected. I have about ten systems that show the warning message in their logs, and had no stability problems so far. Of course I don't like having those messages displayed on console either... I'll look into this for RHEL3 U4 (or reassign it). Sorry for having let this slip through the cracks for so long. -ernie Running RHEL3 AS on HP Proliant DL740 Server after starting HP Proliant Support Package 7.10 Software the system performance tremendously degrades (long delayed responses when working in shells, system load goes over 0.30 after running for a while). Console shows message "i8253 count too high! resetting.." from time to time. Best Regards, Roland *** Bug 102973 has been marked as a duplicate of this bug. *** *** Bug 103024 has been marked as a duplicate of this bug. *** so the only movement on this issue has been marking other reports as dupes of it? Over a year ago, we heard "I'll look into this for RHEL3 U4"... any real progress on this would be appreciated. Also, if all similar reports are marked as dupes of this, then maybe the platform should be changed to include other affected architectures - i386 at least - so that people don't assume this is an athlon only issue. (It isn't.) Eric, the "progress" is that I've reassigned it to someone who will actually have time to work on it. I apologize for not having done this sooner.

I am getting the same error when I am trying to boot RHEL3 under Microsoft Virtual Server 2005. I am using Dell Poweredge 4600 server hardware. AFAIK, no "real progress" can be made on this bug. It's a harmless warning message the kernel prints when it trivially handles a hardware-related issue (reading two i/o ports gives unexpected results). The only way to "fix" it is to remove the printk, or to replace the motherboard. I think kernel developers are happy with the patch (see the links in a previous message of mine), and no one is going to look after it again anytime soon. In summary: there's a hardware bug, the software fixes it, and prints a message after doing so. It's not a bug, it's a fix being deliberately verbose. Hmmm.. If the patch is making it very verbose then the syslog.conf needs to be configured to filter that particular message out. If not the msgbuf would fill and make it extremly difficult to troubleshoot further system issues. A fix for this problem has just been committed to the RHEL3 U8 patch pool this evening (in kernel version 2.4.21-40.6.EL). This issue is on Red Hat Engineering's list of planned work items for the upcoming Red Hat Enterprise Linux 3.8 release. Engineering resources have been assigned and barring unforeseen circumstances, Red Hat intends to include this item in the 3.8 release. An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA. For more information on the solution and/or where to find the updated files, please follow the link below. You may reopen this bug report if the solution does not work for you. http://rhn.redhat.com/errata/RHSA-2006-0437.html |
