Hi all, I have installed FC5 to an brand new IBM xSeries 100 type 8486 server. On short trials It seems to work almost normally except: 1) On boot I always get following messages on console: PCI: Cannot allocate resource region 7 of bridge 0000:00:01.0 PCI: Cannot allocate resource region 8 of bridge 0000:00:01.0 PCI: Cannot allocate resource region 9 of bridge 0000:00:01.0 PCI: Cannot allocate resource region 7 of bridge 0000:00:1c.1 PCI: Cannot allocate resource region 8 of bridge 0000:00:1c.1 PCI: Cannot allocate resource region 9 of bridge 0000:00:1c.1 2) On short trial the server seems to work quite normally except when I try to start X. startx (or gdm at runlevel 5) freezes most of the times (not always) and leaves screen blank and in unusable state. I still can login to the box through ssh (Server works slowly in this state). Following gets logged during X crash: kernel: [drm] Initialized drm 1.0.1 20051102 kernel: ACPI: PCI Interrupt 0000:0a:04.0[A] -> GSI 16 (level, low) -> IRQ 16 kernel: [drm] Initialized radeon 1.22.0 20051229 on minor 0 kernel: irq 20: nobody cared (try booting with the "irqpoll" option) kernel: [<c0145ac7>] __report_bad_irq+0x2b/0x69 [<c0145c88>] note_interrupt+0x183/0x1af kernel: [<c01455f2>] handle_IRQ_event+0x23/0x4c [<c01456c8>] __do_IRQ+0xad/0xdd kernel: [<c0105eee>] do_IRQ+0x60/0x7b ======================= kernel: [<c0104786>] common_interrupt+0x1a/0x20 kernel: [<c0102f65>] mwait_idle+0x1f/0x33 [<c0102f2d>] cpu_idle +0x8f/0xa8 kernel: [<c03c8715>] start_kernel+0x2fe/0x304 <3>handlers: kernel: [<c026e461>] (usb_hcd_irq+0x0/0x50) kernel: Disabling IRQ #20 This has happened with every kernel available to FC5 so far. Since this is a box I promised one person to setup as a linux server and it has been already sitting here one month unused, I wonder if anybody knows if it is safe to put it under 'production-use' (If no X is used and just acting as a pure mail/web server)? I have tried some boot options (e.g. acpi=off pci=noacpi acpi=noirq, but on the kernels I tried they did not help). Added comments on error #186557 BR, Jouni
