Hardware :: IRQ / Interrupt Conflict With MegaRAID
Feb 3, 2010
Ever since Linux kernels beyond 2.6.24.3, I've been unable to boot my HP Netserver LH3. It gives a kernel panic with a variety of messages that always include
"common_interrupt+0x38/0x39"
I tried everything from updating the BIOS and firmware, to myriads of differing kernel configurations (at 4 hours per compile, imagine the agony).
I also tried booting with every combination of the kernel boot parameters acpi=off, noapic, nolapic, irqpoll, etc., that I could imagine. No dice. In final desperation, I began unplugging PCI cards one by one before finally disconnecting the SDLT drive from the Netraid SCSI. It seems that in later kernels or versions of udev, sharing the SCSI bus with the LH3 drives causes conflicts. I have an additional AHA SCSI card in the machine, so will try connecting the SDLT to that and see how it goes.

I am installing openSUSE 11.4 on a Supermicro Quad core board with a pci-e LSI megaraid card and the installation goes through fine but once the pc reboots and boot off the hard drive a boot error occurs now i installed openSUSE 11.2 and all is well. What is wrong in 11.4.

Problem with megaraid controller and Dell2850, all that I can see on this screenshot: [URL]. All drives successfully passed verifying from LSI controllers (Ctrl+A at startup), also I tried to boot from rescue live cd and mount all the mirrored drives and check it by fsck - ok.

I have looked thru the forums and I am not sure if LSI 8204ELP definitely works with Centos 5.3 or 5.2 or 5.1 or not. Can anyone who has had a positive experience with this hardware combination give some feedback etc. mobo is supermicro c2sbx [URL]

I have Ubuntu 10.04 and MegaRAID controller. The only tool I have is the notorious MegaCli. I need to be emailed when some disk has failed in the RAID array. How to set that up?

How to load the driver for this SAS+SATA controller during install, I tried loading the supplied 5.0.5 driver from LSI but it appears that the options in the provided list do not provide actual support for the 5.0.7 release. Anyone having luck with the 9280 controller. I checked kernel.org and saw that supports is getting added for the upstream release of the kernel but wonder if anyone was able to workout a patch for the present Debian kernel in order to install the driver as the OS loads.

I need cause an interrupt on a serial port. If I put a single HIGH on the RX pin, will that cause one? I all ready use the 4 control lines for data.Hope I am making sense?

Is there a way to interrupt the boot sequence, or execute it line by line? Alternatively, after a command has executed and the scree fills up, is there any way to "page up" on the screen?

Assume: 1) Multi-cpu environment 2) Process that gets interrupted, is the same process that executes the interrupt handler, so I guess technically nothing gets interrupted except what the process was doing before, but it is still executing as it is executing the handler. 3) There is no top or bottom half, when an interrupt takes place the handler is invoked, executes, then return from interrupt, simple as that.
Why would sleeping the handler (puts in sleep queue, context switch to next runnable process) be a bad idea?

The following message: [ 2364.064174] hda-intel: spurious response 0x0:0x0, last cmd=0x524011 or one very similar. The "last cmd" element may vary, though not necessarily. I'm currently running Lucid - Kubuntu with 2.6.32-22-generic kernel. The CPU is an Intel(R) Core(TM)2 Duo CPU E4500 @ 2.20GHz, 1 Gb ram, and two hard drives an Hitachi SATA (600 GB) and a WD PATA (350 GB). I've found several threads regarding the error message and the sound system on intel based systems. I would like to know whether AMD systems face a similar issue.

I'm trying to open ttySx from an interrupt.the kernel crashes. is it possible to open/write to serial port from interrupts ? I think it crushes because when I try to open the device there is a mutex lock which cause the kernel to crash , am I right

I have written a Linux kernel module (in Linux 2.4, Red Hat 9) which does the followings: It takes srcIP, sourceport, destIP, destport and loadvalue as command line arguments. If configured load value is greater than 1, it creates different channels (i.e. No of UDP channels created equals to configured load value), assign different source port and destination port to different channels and send UDP datagram in different channels. Say for example the configured parameters are as follows srcIP=10.17.17.43 destIP= 10.17.17.44 sourceport=10000 destport= 20000 loadvalue=2.
Then it creates two UDP different channels and transmits UDP packets (in every 20 milliseconds) to destination IP address (i.e., 10.17.17.44) with source port 10000, destination port 20000 in one channel and source port 10002, destination port 20000 in another channel. When I configure to pass ?loadvalue=500? and run the module, I get the below kernel panic message in system log file (i.e., var/log/messages) 0>Kernel panic: Aiee, killing interrupt handler! In interrupt handler - not syncing. Running the same linux kernel module ,in 1000 loadvalue, I get this message, eth0: Out-of-sync dirty pointer, 49937 vs. 49954 in text console. I am unable to catch the root cause of these problems and how will I solve these?

I have installed a Fedora Core 12 Linux system onto a RAID 1 file system. I now need a way of getting an notification if the disk fails. Is there an SNMP MIB that covers Intel RAID? I have done the searching but still the answer alludes me.

I have a box with Novell Suse linux installed. It asks for username and password I do not have and cannot figure out. I also have a SantaFe distro CD with which I would like to replace the Suse on the box. I cannot get the box to BIOS to change the boot order to boot from CD. I would like to break free of Windows, but can't seem to get there from here...

I have a computer that freezes for about 41 seconds frequently. There's no logs other than a rtkit complaining about a starving bird. Then I started running vmstat, below is when the glitch happens. Any ideas on what could be causing the very high "in: The number of interrupts per second, including the clock." all of a sudden?

I have written interrupt handlers for a keyboard as well as the serial port RS232.
I have seen the book written by O'Reilly w.r.t the device drivers.
I wanted to know *exactly* what parts of Linux kernel should i understand well for having a crystal clear view of writing any kind of device driver ?

I have random crashes since I upgraded from Fedora 11 to Fedora 12.I searched the internet to try to find the root cause of the problem.I created this bug report:URL...However, no comments were added how to solve the problem.Enabling msi for nvidia and hda-intel made the system much more stable. But I still experience sometimes crashes.I do not know how to enable msi for uhci_hcd:usX, which is still sharing interrupts with ata_piix and ehci_hcd:usbX.Have you some hints? I hate it when my Fedora Linux system is crashing randomly.

Ctrl-c with middle mouse button (MMB) trigger in running bash script trigger.
The key combination Ctrl-C or "^C" with the keyboard triggered on a running bash script stands for "signal interrupt" (SIGINT) and terminates the process.
For my workflow in the test phase, how I could do that with the MMB-Buffer, followed by the modified script command:
Code: Select allscript runs
script runs
script runs
Signal interrupt and rerun with MMB trigger:
Code: Select all^C; ./script.sh
modified script runs
modified script runs
does not work and 2 hours meta-crawlers

On my system (OpenSUSE 11.4 - kernel 2.6.37) ifconfig indicates different interrupt number for eth0 than proc aqd sys file system.
ifconfig indicates 17:
proc fs indicates 43:
sys fs indicates 43:
Relevant part of lspci -vv output for irq 17 (this belongs to wlan0 and not to eth0):

I am doing some Linux kernel programming for my research project. I need to record the timestamp (by using cpuid and rdtsc) when an interrupt handler (top half) is first invoked. Due to the time critical nature of the problem itself, I have to do the timestamping inside the interrupt handler itself (the first operation when the handler is called). However, I understand that tasks that are not so time critical should be deferred to a tasklet function (bottom half) for processing because other interrupts are disabled in a (top-half) interrupt handler. I am currently out of idea on how I can pass the timestamp information that I have obtained in the interrupt handler to the corresponding tasklet function.
