------- Comment #14 from [EMAIL PROTECTED] 2008-02-04 00:39 -------
Thanks for the info.
From the info in comment #3, #12 and #13 OS will report the following debug
message:
> PCI: Cannot allocate resource region 7 of bridge 0000:00:1c.0
> PCI: Cannot allocate resource region 7 of bridge 0000:00:1c.0
The above debug message is caused by bios configuration . The details are
listed in the following:
a. The PCI bridge (1c.0 and 1.c3) is programmed by BIOS. For 1c.0 : The IO
resource ranges from 0 to 0xfff. Memory resource ranges from 0 to 0xfffff. For
1c.3: there is no IO resource defintion and memory resource ranges from
d0000000 to d00fffff.
b. The memory&IO resource will be reserved by OS in the phase of PCI
initialization. If the resource can't be reserved , OS will report the error
message. For example: the IO resource (0-0xfff) is reserved for 1c.0 bridge;but
unfortunately the IO resource(0-0xfff) is used by other devices(RTC timer; DMA;
8259). So the OS will report the above error essage.
Of course the above message won't break anything because there is no PCI
device behind the PCI bridge (1c.0). The message is confusing.
Since the message is caused by BIOS configuration and won't break anything,
the bug will be rejected.
Thanks for the info.
