Pentium 200, 32 mb ram, 2 gb hda, cdrom hdc Redhat 8.0, stock kernel (2.4.18-14) Card works fine in another Redhat 8 box with 2.4.18-17 or 2.4.18-18 kernel. May be an already fixed bug? Will test. Description of problem: The message "Spurious 8259A interrupt: IRQ7" appears on the console, then hda:lost interrupt every one to two seconds. If DMA is enabled, an additional message about lostirq_func 13 only supported or some such. Have twice seen "Unknown interrupt" instead and an immediate hang of the console. Otherwise, "login" or other running console programs respond until they access the disk, but ssh session that triggered bug is immediately hung. See below for steps to reproduce. Hardware: lspci reports the card as 00:0a.0 Ethernet controller: Lite-On Communications Inc LNE100TX (rev 20) Card appears to be labeled as a NetGear FA-310. Tulip module is definitely loaded. Rest of the box is: 00:00.0 Host bridge: VIA Technologies, Inc. VT82C585VP [Apollo VP1/VPX] (rev 10)00:07.0 ISA bridge: VIA Technologies, Inc. VT82C586/A/B PCI-to-ISA [Apollo VP] (rev 02) 00:07.1 IDE interface: VIA Technologies, Inc. VT82C586B PIPC Bus Master IDE (rev 02) 00:08.0 Communication controller: PCTel Inc HSP MicroModem 56 (rev 01) 00:0b.0 VGA compatible controller: Trident Microsystems TGUI 9660/938x/968x (rev d3) Issues occur with or without the pctel modem, and also occur with a second identical card in the box at the same time, or with the second card alone. No problems appear when card is replaced by a 8139too card. Note that the system is an Apollo VPX, has "VXtwo" labels on the chipset. I googled several reports of issues with DMA on this chipset, but this problem also occurs with DMA disabled. Have been unable to reproduce this bug other than over ethernet. Have also mucked with BIOS settings/timing/PnP OS, no change. How reproducible: Always Steps to Reproduce: 1. ssh into box over ethernet card in question 2. login works ok 3. hold down CR for a few seconds (3 to 15 key repeats) 4. message appears, and login is completely unresponsive Bug filed after discussion on bug #75481.
Have confirmed that the same box with kernel 2.4.18-18 hangs during network activity. Machine is currently headless, so cannot confirm error messages. Trying to find a way to check the console. Andrew
IRQ routing not IDE I suspect
Any comments on how to confirm IRQ routing problem? I have a monitor on the machine and can test. Have upgraded machine to RH 9, have not tested for issue yet.
Thanks for the bug report. However, Red Hat no longer maintains this version of the product. Please upgrade to the latest version and open a new bug if the problem persists. The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, and if you believe this bug is interesting to them, please report the problem in the bug tracker at: http://bugzilla.fedora.us/
