...IRQ routing acpi_irq_balance [HW,ACPI] ACPI will balance active IRQs -- default in APIC mode pci= noacpi [IA-32] Do not use ACPI for IRQ routing or for PCI scanning. noapic [SMP,APIC] Tells the kernel to not make use of any IOAPICs that may be present in the system. noirqbalance [IA-32,SMP,KNL] Disable kernel irq balancing This is all more than a little confusing to me. It appears that the kernel's IRQ balancing is contingent on ACPI and APIC, but I'm far from positive about this conclusion. If someone could explain to me how these different components int...

Hello Adam, i have the same problem, you written on 26. April. Could you solve the Problem till now? Here some Info about my system: Dell PE 2850, Dual CPU, 4GB RAM. Perc4Di with 4Disks-Raid5 and 2Disks-nonRaid Dom0 and all DomUs are loading fine. (2.6.16) At random times the hole maschine hang. I was not able to capture anyting at this time. I have self compiled Kernel without initrd. I

...initrd and so on and tried to boot the system with Dom0 with xen-linux-2.6.12.6-xen. XEN loads and starts to boot up the kernel but then the kernel crashes. I connected a serial console and logged the output (see attachement). I played around with various xen and kernel parameters like acpi=off, noirqbalance, nosmp, nousb, noapic, apic=..... with no success. I thought of an ACPI related problem and updated system bios to latest bios from January 2006. Nothing helped. If I want to boot to my normal system after such a crash I''ve to power the machine off (not reboot !) and erase the BIOS PCI Ta...

Hi, I''m trying to get VGA passthrough to work to an XP x64 guest, and I''m seeing "interesting" things happening. I''m using the kernel and userspace tools from here: http://xen.crc.id.au/support/guides/install/# on Scientific Linux 6. I gave up on trying to get an Nvidia card to work in the guest having read about the extra patches required to get a

Of course I tried irqpoll, but no use. Currently I''m using ''noirqbalance noirqdebug'' as kernel parameters as these two reduce the above messages, but they still occur. Data written on disks seems to be alright, and I think, this doesn''t concern my controller, but it''s strange anyways. This doesn''t arise with my distribution''s...

Hi, i have big trouble with a Debian Lenny dom0 and latest kernel 2.6.32.19 with xen-4.0.1rc5. Due some reason the system freezes from time to time. I used kernel 2.6.31.9 with xen-3.4.2 before. The machine doesn''t write anything to serial console so there are no errors or something like that. Perhaps there is something to see from the logs ... Hardware Board: Intel DQ45CB CPU:
