Description of problem:
For some systems - especially during the install of FC2 - it would be
very helpful to config UP IO-APIC support into the kernel. This would
help when some of the legacy PIC support is not correct (some BIOSs)
or not there at all (some hardware).
According to the "notes" related to this option, nothing is harmed by
including it and in some cases for some devices, this may be the only
way to access the hardware (interrupts) when running the install
kernel (UP kernel). Of course this option is on (correctly) in the
SMP kernels and no change is requested (or needed) with the SMP kernels.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Use hardware with Legacy PIC support not functioning (remain nameless).
3.If doing a network install and NIC(s) have no interrupts - bad news.
Actual Results: Unable to do network installations.
Expected Results: If UP IO-APIC support were configured, the NIC(s)
would function and the network installation would be possible (on this
unfortionately this breaks too many machines out there, so we're not
going to be able to do this.
Agreed - even a blacklist would need to be a whitelist or we would
have megabytes of dmi blacklist tables.
As regards 440GX this is fixed properly in 2.6.7
Fedora Core 2 has now reached end of life, and no further updates will be
provided by Red Hat. The Fedora legacy project will be producing further kernel
updates for security problems only.
If this bug has not been fixed in the latest Fedora Core 2 update kernel, please
try to reproduce it under Fedora Core 3, and reopen if necessary, changing the
product version accordingly.
