Patch #1 is already in RHEL3 U4... Patch #2 has not been accepted upstream (yet) -- will have to investigate before I can push it in RHEL3... Patches for #2 posted internall and upstream on 11/17... HP has asked that this be fixed in rc1 if possible -- it is NOT a blocker. Arg ! Wrong Release. HP asks if this can be in RHEL3 U4. It's too late. Making U5 blocker. A fix for this problem has just been committed to the RHEL3 U5 patch pool this evening (in kernel version 2.4.21-27.3.EL). 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-2005-294.html |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux ia64; en-US; rv:1.7) Gecko/20040917 Firefox/0.9.3 Description of problem: The existing tulip driver (0.9.15-pre12) in 2.4.21-20.EL kernel has two known bugs: 1) In the ifconfig down path, tulip_remove_one() calls pci_free_consistent() before calling unregister_netdev(). Fix is move the unregister_netdev() a few lines up in the source. Jeff Garzik original sent me this fix more than 6 monthes ago. This fix should be in all RHEL releases by now. 2) tulip_stop_rxtx() doesn't wait for DMA to fully stop like the function call name implies. Charlie Brett (HP) gets credit for finding this last April. I submitted a patch to Jeff Garzik but don't recall it getting accepted or what the outcome was. Patch is still available from: ftp://ftp.parisc-linux.org/patches/diff-2.6.6-tulip_stop_rxtx thanks, grant iod00d grant.grundler Version-Release number of selected component (if applicable): 2.4.21-20.EL How reproducible: Always Steps to Reproduce: 1. from system A, generate large packets (e.g. pktgen, "ping -b -f -s 1492") 2. on system B (HP ia64): while : do date ifconfig eth4 down sleep 5 ifconfig eth4 up sleep 10 done eth4 is a tulip device. Actual Results: HP ia64 machine will MCA in minutes if no seconds. Expected Results: system should not MCA. Additional info:
