Summary: ACPI interrupt storm Product: ACPI Version: 2.5 Kernel Version: 2.6.29.2 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Config-Interrupts AssignedTo: acpi_config-interru...@kernel-bugs.osdl.org ReportedBy: cshor...@gmail.com Regression: No Created an attachment (id=21264) --> (http://bugzilla.kernel.org/attachment.cgi?id=21264) acpidump output Further details as requested... Slight change of conditions - turned off the fglrx kernel module and compiled a 2.6.29.2 kernel. Experienced the same "storm". interrupts, dmesg and acpi information attached. The following text is duplicated from the linux-acpi mailing list for reference: Subject: System overloaded with ACPI interrupts Hello, I think I'm experiencing some kind of ACPI issue, I haven't been able to identify a series of actions that causes this. I first noticed the problem when looking at 'top' - seeing kacpi at the top of the process list (followed by kacpi_notify). I have powertop installed, the dump is attached - acpi interrupts seem to be excessive. The computer is perhaps not the best machine: Arima M620-DC. I think the same chassis may be used by a number of other manufacturers. The system does not boot in this state - it occurs rather unpredictably after high CPU loads. I had thought this was a CPU temperature issue and replaced the thermal paste of the heatsink, which improved matters. I have also blacklisted the following modules: blacklist i2c_i801 blacklist yenta_socket The kernel reports a conflict between ACPI SBUS and i2c_i801. I forget why I disabled yenta_socket, but I don't use the card reader. The OS is openSuSE 11.1 with the 2.6.27.21-0.1-default kernel installed. I've also tried booting the system with acpi=noirq. This gives a 'irq 5: nobody cared' and the wireless card (ipw2200) then doesn't work. My normal kernel command line contains the following parameters: hpet=force lapic vga=0x317 This is what all the attached logs are generated from and when my system functions with all devices working. I have also disassembled the ACPI tables. I can post them if required? Hopefully someone can suggest a temporary solution or a permanent one? Thanks, Chris The response: hi, please try a recent vanilla kernel and see if it's reproducible. 2.6.29 would be a good choice. if the problem still exists in 2.6.29 kernel, please attach the output of dmesg and "grep . /sys/firmware/acpi/interrupts/*" after the interrupt storm occurs. please also attach the acpidump of this laptop. it would be great of you can open a new bug report at http://bugzilla.kernel.org/enter_bug.cgi?product=ACPI and attach all the info there. -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. ------------------------------------------------------------------------------ The NEW KODAK i700 Series Scanners deliver under ANY circumstances!
