--- Comment #28 from M. Vefa Bicakci <bic...@superonline.com> 2009-03-30 01:31:13 --- Hello, I apologize for not responding earlier; I wanted to gather more data before posting a message. I took 2.6.24's source and reduced its spurious interrupt limit to 10 in "kernel/irq/spurious.c". I called this 2.6.24-suspect. Testing this kernel was not helpful because after a certain amount of uptime and with a certain pattern of network activity, iwl3945 started to print error messages which are appended to this message. After a few "rmmod iwl3945" and "modprobe iwl3945" cycles, I got crashes. This occurred at least three times. In addition to this, I got the following "nobody cared" message one time while testing 2.6.24-suspect: === 8< === irq 17: nobody cared (try booting with the "irqpoll" option) Pid: 29141, comm: Xorg Not tainted 2.6.24-suspect #1 [<c0157ee6>] __report_bad_irq+0x36/0x75 [<c0158139>] note_interrupt+0x214/0x273 [<c01577e9>] handle_IRQ_event+0x23/0x51 [<c01586af>] handle_fasteoi_irq+0x85/0xa5 [<c010672f>] do_IRQ+0x55/0x6e [<c0184a4f>] sys_ioctl+0x45/0x5e [<c010497f>] common_interrupt+0x23/0x28 ======================= handlers: [<f8882d7a>] (usb_hcd_irq+0x0/0x56 [usbcore]) [<f8ddccfd>] (i915_driver_irq_handler+0x0/0x18e [i915]) Disabling IRQ #17 === >8 === However, this message occurred when I was trying CompizFusion - I was switching it on and off. To be honest, I don't know if this "nobody cared" message was printed because of the same problem as the one I had when I opened this bug report, or because 10 is a really low limit. The longest uptime I was able to achieve with 2.6.24-suspect before I got crashes was 4 days. Because wireless is essential for me, I didn't continue my tests with 2.6.24-suspect. I then used Sidux's 2.6.28.7 based kernel, unmodified. After an uptime of 15 days without any problems, I decided to test vanilla 2.6.28.7 with a low spurious interrupt limit. This time I used 99 as the spurious interrupt limit. I called this kernel 2.6.28.7-spurious. I am still running this kernel, and my current uptime is 15 days. So, in other words, I haven't been able to reproduce this problem with 2.6.28.7. (Yet?) However, I am going to try 2.6.24.7 and 2.6.29 with 99 as the spurious interrupt limit, so please do not close this bug report yet. Any suggestions on which of these two versions I should test next, how much time I should wait before deciding that I cannot reproduce this problem, and what would be a good spurious interrupt limit (instead of 10 or 99) ? There is one more important thing which happened: Before testing 2.6.24-suspect, I upgraded my laptop's BIOS. I can downgrade the BIOS if it becomes necessary to confirm the role of the BIOS version in this problem. Once again, sorry for my late response. Thank you, M.
