From mboxrd@z Thu Jan 1 00:00:00 1970 From: "alpha @ steudten Engineering" Subject: Kernel panic on alpha cpu 2.6.13-2.6.15 not in 2.6.10 Date: Fri, 20 Jan 2006 13:58:43 +0100 Message-ID: <43D0DE83.6000009@steudten.org> Mime-Version: 1.0 Content-Transfer-Encoding: 7bit Return-path: Sender: linux-alpha-owner@vger.kernel.org List-Id: Content-Type: text/plain; charset="us-ascii" To: LinuxAlpha , LKML , becker@scyld.com Was: "Kernel crash on alpha cpu 2.6.13-2.6.15" Part 2: The system has crashed again today with "kernel panic - not syncing: Aiee, killing interrupt handler!" After 3 days uptime! Is there any way with do_exit() to find out, which interrupt or kernel code this is? Is it possible to print out a kernel stack trace in do_exit()? The Magic Keys don't work in the normal way for the alpha. Original Mail: Hello Summary: alpha cpu 64 Bit kernel-2.6.10: ok kernel-2.6.13-2.6.15: problem eth0: 3Com Corporation 3C905B Fast Etherlink XL 10/100 Kernel crash, reboot problem due to kernel-log-buffer flooted with message. No problem on x86 with same network card. Kernel not stable on alpha cpu! With hardreset (power-off) everything is ok, until the next time. Detail: kernel-2.6.15: Kernel crashs after 5-15days, no message is logged in syslog (klogd -2 -p -c 3). Autoreboot after crash is active and when the kernel boots again, the syslog is flooted with the messages: kernel: eth0: Host error, FIFO diagnostic register 0000. kernel: eth0: PCI bus error, bus status 40000020 kernel: eth0: Host error, FIFO diagnostic register 0000. kernel: eth0: PCI bus error, bus status 40000020 kernel: eth0: Host error, FIFO diagnostic register 0000. kernel: eth0: PCI bus error, bus status 40000020 kernel: eth0: Host error, FIFO diagnostic register 0000. kernel: eth0: PCI bus error, bus status 40000020 kernel: eth0: Host error, FIFO diagnostic register 0000. [..] About 20 lines per second! -> BTW: Why this is not catched from klogd/syslogd to one entry per second? The text is in "drivers/net/3c59x.c line 2149 (2.6.15): 3c59x.c:2149: printk(KERN_ERR "%s: Host error, FIFO diagnostic register %4.4x.\n", A diff between 2.6.10 and 2.6.15 3c59x.c shows a lot of lines changed, and the i/o calls like "inw" changed to "ioread16" aso - maybe this is a probem. 00:09.0 Ethernet controller: 3Com Corporation 3c905B 100BaseTX [Cyclone] (rev 30) Subsystem: 3Com Corporation 3C905B Fast Etherlink XL 10/100 Flags: bus master, medium devsel, latency 32, IRQ 24 I/O ports at 8c00 [size=128] Memory at 000000000a064000 (32-bit, non-prefetchable) [size=128] Expansion ROM at 000000000a020000 [disabled] [size=128K] Capabilities: [dc] Power Management version 1 Regards Thomas
