Subject: [Linux-ia64] null pointer in iosapic_pci_fixup()
Date: Mon, 26 Nov 2001 16:17:26 +0000 [thread overview]
Message-ID: <marc-linux-ia64-105590698805543@msgid-missing> (raw)
When a device is found behind a pci/pci bridge and this device has no
IRQ decribed in the ACPI table, Linux prints a warning message:
" PCI: Couldn't map irq for (...)"
unfortunately there is a null "bridge" pointer at that point. This makes the
system hang in release 2.4.9 and have a wrong print of bus , device
and irq in kernel 2.4.13.
A posssible patch could be:
--- linux-2.4.13-ori/arch/ia64/kernel/iosapic.c Mon Nov 26 17:09:49 2001
+++ linux-2.4.13-new/arch/ia64/kernel/iosapic.c Mon Nov 26 16:42:40 2001
