Subject: [Linux-ia64] pci/pci bus not seen with kernel 2.4.10
Date: Tue, 02 Oct 2001 16:24:51 +0000 [thread overview]
Message-ID: <marc-linux-ia64-105590698805292@msgid-missing> (raw)
I have problems with pci/pci bridge not seen with kernel 2.4.10 on
ia64 (was OK on 2.4.9). This is due to modifications in ACPI driver:
the acpi_cf_associate_prt_to_bus() routine calls
acpi_os_read_pci_configuration() with width = 1, but the
acpi_os_read_pci_configuration() routine expects width = 8 for 1 byte.
I patched and could get the pci/pci buses configured.
