http://bugzilla.novell.com/show_bug.cgi?id=596329 http://bugzilla.novell.com/show_bug.cgi?id=596329#c0 Summary: boot delayed on PREEMPT RT Kernel (udevadm keeps working and working) Classification: openSUSE Product: openSUSE 11.2 Version: Final Platform: PC OS/Version: openSUSE 11.2 Status: NEW Severity: Normal Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: fi@igh-essen.com QAContact: qa@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; U; Linux i686; de; rv:1.9.1.6) Gecko/20091201 SUSE/3.5.6-1.1.1 Firefox/3.5.6 we installed OpenSuSE 11.2 on different, but recent PC hardware. Booting the default kernel ( 2.6.31.12-0.2-desktop ) works fine. But booting the PREEMPT RT Kernel (2.6.31-rc8-rt9-3-rt) reproducibly gives remarkable delays (about two minutes) compared to the default kernel mentionaed above. During delay udevadm sends the following info to console: ... Creating device nodes with udevd udevadm settle - timeout of 30 seconds reached, the event queue contains: /sys/devices/pci0000... ... (up to 10 lines like the one before) ... udevadm[551]: error sending message: Connection refused udevadm settle - timeout of 30 seconds reached, the event queue contains: /sys/devices/pci0000... ... (up to 10 lines like the one before) ... udevadm[552]: error sending message: Connection refused udevadm settle - timeout of 30 seconds reached, the event queue contains: /sys/devices/pci0000... ... (up to 10 lines like the one before) ... resume device not found (ignoring) udevadm[551]: error sending message: Connection refused udevadm settle - timeout of 30 seconds reached, the event queue contains: /sys/devices/pci0000... ... (up to 10 lines like the one before) ... Waiting for devive /dev/sda1 to appear: ok. (please note the double space after "resume device". Is there something missing?) Then the systems do boot and work as usual. Reproducible: Always Steps to Reproduce: 1. install default OpenSuSE 11.2 2. install default PREMPT RT Kernel 3. boot Actual Results: delay and error messages during this delay. Expected Results: boot duration should not heavily depend on the kernel (PREMPT RT Kernel or Desktop Kernel) -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The first message from my report above ("Creating device nodes with udev") appearing immediately after "doing fast boot" comes from ./boot/04-udev.sh contained in the initrd. Also the 30-seconds timeout is defined only in the initrd. So I'm pretty sure, that udev is run from initrd. Also there was nothing special in installing the PREMPT RT Kernel. I did that by YaST (or Zypper, don't remember exactly). The initrd has been built during the Kernel installation. I did no customization nor manual configuratiuon. Here are some details that may be interesting: $ cat mkinitrd.config -k /boot/vmlinuz-2.6.31-rc8-rt9-3-rt -i /boot/initrd-2.6.31-rc8-rt9-3-rt $ grep -v '^#' /etc/sysconfig/kernel INITRD_MODULES="thermal ahci ata_piix ata_generic piix ide_pci_generic processor fan" DOMU_INITRD_MODULES="xennet xenblk" MODULES_LOADED_ON_BOOT="" ACPI_DSDT="" SKIP_RUNNING_KERNEL="" Regards Torsten -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The problem is that unless it's in debug mode, then it doesn't dump anything on stderr. Can you boot with "linuxrc=trace" and report what you see? -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

http://bugzilla.novell.com/show_bug.cgi?id=596329 http://bugzilla.novell.com/show_bug.cgi?id=596329#c5 --- Comment #5 from Jeff Mahoney 2010-04-23 13:30:01 UTC --- The easiest way, if you have another system, is to use a serial console to capture the output. You boot with "console=ttyS0,115200 console=tty0" on the command line and use the serial terminal program of your choice to capture it. Personally, I just use screen(1) with logging enabled: screen -L /dev/ttyS0 It will log everything into screenlog.<some number> -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
