This does not affect every configuration. It is indeed the same ask as in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1934620--I was not aware that this had been requested in the past, and given that we are still seeing issues with this, I thought it was worth asking.
I don't know of any cases in which it is desirable to have PCI realloc enabled, at least on Dell systems. I presume that is helpful on some systems where BIOS doesn't allocate address space to PCI devices, but there is enough unused address space available to the PCI busses that it reallocations succeed. The kernel reallocation algorithm doesn't appear to be very robust in that it will assign space that isn't needed on some devices, then fail to have enough remaining for others--but when this happens, it doesn't revert to the original allocations; rather, some devices just fail. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2122171 Title: PCI realloc failing To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2122171/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
