These bugs are being closed since a large number of updates have been released after the FC5 test1 and test2 releases. Kindly update your system by running yum update as root user or try out the third and final test version of FC5 being released in a short while and verify if the bugs are still present on the system .Reopen or file new bug reports as appropriate after confirming the presence of this issue. Thanks was test3 any better ? No. I did try fc5t3 and the problem is still there. I don't know what the adverse effects of the workaround "noapic acpi=off" are except I think it is the reason for power not being turned off automatically on shutdown. My other computer is identical to the above but runs FC4 i386. I just up2date'd both incl. latest kernel-2.6.16-1.2069_FC4. Results i386: It now exhibits the same above problem unless I pass "noapic acpi=off". x86_64: It now hangs already right after having displayed "Booting the kernel." during bootup - whether or not I pass "noapic acpi=off". Maybe this is helpful. I just tried both i386 and x86_64 of the latest SuSE - 10.1 beta 9. And neither exhibits this problem. Maybe also this is helpful. I just again tried giving this problem another shot. This time with FC5 i386 final but still on the same above hardware. FC5 final wouldn't even install. Hung at the point where it is about to install packages and also if I pass noapic acpi=off. I then searched the BIOS and found an option named IOAPIC. I disabled that and that did it. With that FC5 installed and runs - also without passing noapic acpi=off. I then reset the BIOS back to factory defaults i.e. re-enabled the IOAPIC option. With that FC5 again hangs and the console says "ACPI: Unable to load the System Description Tables" but if I then pass noapic acpi=off then the console does not show that message and FC5 does not hang. A new kernel update has been released (Version: 2.6.18-1.2200.fc5) based upon a new upstream kernel release. Please retest against this new kernel, as a large number of patches go into each upstream release, possibly including changes that may address this problem. This bug has been placed in NEEDINFO state. Due to the large volume of inactive bugs in bugzilla, if this bug is still in this state in two weeks time, it will be closed. Should this bug still be relevant after this period, the reporter can reopen the bug at any time. Any other users on the Cc: list of this bug can request that the bug be reopened by adding a comment to the bug. In the last few updates, some users upgrading from FC4->FC5 have reported that installing a kernel update has left their systems unbootable. If you have been affected by this problem please check you only have one version of device-mapper & lvm2 installed. See bug 207474 for further details. If this bug is a problem preventing you from installing the release this version is filed against, please see bug 169613. If this bug has been fixed, but you are now experiencing a different problem, please file a separate bug for the new problem. Thank you. I have restarted many times and run without "noapic acpi=off" since notified by comment #7 - and the problem has not reoccurred. it would be interesting to know if you really need both those options. If it's jut the noapic option that's causing the problem to go away, there was a patch in the update kernel I pushed out last week (2.6.18-1.2239.fc5) which may also solve your problem without you passing any options at all. I can't test because the problem no longer shows. Again, I have 2 systems of identical hardware as specified above. On one I still had the fc5 i386. I up2date'd it to 2.6.18-1.2239.fc5, rebooted it 10 times without "noapic" and "acpi=off", exercised it in between reboots and the problem did not show. On the other I'm now running 2.6.18-1.2849.fc6 i386 and also without "noapic" and "acpi=off" and it doesn't have the problem anymore either. I've attached the output of dmesg from the fc6 system - in case usefull. The problem is solved as far as I can tell. Created attachment 141870 [details] output of dmesg referenced in comment #10 |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (compatible; Konqueror/3.5; Linux) KHTML/3.5.0 (like Gecko) Description of problem: My system hangs. I have not yet not experienced it not to hang and I've never seen it recover. It happens at random places - mostly during bootup at the stage where the system is starting various services - but a few times also after the desktop is running. Some of the "hangs" are silient. The console says Starting service abcxyz [OK] and then silence. Other "hangs" are followed by a message every 30 seconds - mostly this one ata1: command 0x35 timeout, stat 0x50 host_stat 0x24 but also this one ata1: command 0x25 timeout, stat 0x50 host_stat 0x24 I googled and then tried passing first noapic and then instead acpi=off as kernel argument. In both cases I have not yet experienced the problem. My system: OS: FC5Test2 x86_64 Motherboard: MSI K8NGM-V (Nvidia C51G/MCP51G aka 6100/410) Harddisk: Hitachi HDT722525DLA380 (SATA 300) CPU: Sempron 2800 Memory: 1GB Other hardware, cards, connections, etc: None - except PSU, vga, mouse, keyboard and Ethernet. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Install FC5Test2 on hardware as described in the "Description" 2. Boot 3. Actual Results: The system hung. Expected Results: The system should not have hung. Additional info: The motherboard and chipset model is relatively new.
