Red Hat Bugzilla – Bug 83231
install hangs on SMP system
Last modified: 2005-10-31 17:00:50 EST
Description of problem:
I have two SMP systems where the install hangs (both gui and text). I have
tried local cdrom, hard drive, and nfs installs. Both of these systems have
successfully installed 8.0.92. The install hangs are various places but usually
when it is starting X.
I suspect that the problem is really a kernel problem but it happens at various
places during install.
The cdroms have been mediachecked OK and successfully used to install on non-smp
Version-Release number of selected component (if applicable):
One system is a dual PIII (933MHz) with 900MB ram and ATI 7500 video. The other
is a dual PII (400MHz) with 300MB ram and ATI Rage video.
Both successfully install and run 8.0 and 8.0.92.
Anything obviously wrong printed out on any VCs?
Does sysreq tell you anything?
I just ran a test on one of the systems. I found on VC4 messages saying
hdd lost interrupt
multiple times. hdd is the cdrom drive. I will check the other system in a
couple of minutes. Strange that this occurs only with SMP systems. I also
tried using "linux ide=nodma askmethod" and it hung as soon as it tried to get
to the cdrom.
BTW, I believe the Red Hat mailing list servers are constipated again.
OK, similar thing on the second (dual P-III) system. Two happenings:
1. Did "linux ide=nodma askmethod" and then selected local cdrom. This hung
solid (freeze) when it got the first X screen up with the mouse. I could do
nothing ... could not switch to VCs.
2. Did "linux ide=nodma askmethod text" and then again selected Local cdrom.
This got further -- to actual install. While formating "/" (only one partition
5GB partition defined), it hung about 75% into formatting. Checking VC4, I found:
Lots of messages saying
<6>ide: no cache flush required
<3>hdb: lost interrupt
hdb is the drive containing the "/" partition.
BTW, this system (and the other one) both have 8.0 and 8.0.92 installed and running.
OK, I am changing this to the kernel component. Thanks to Smooge, the problem
appears to be released to APIC. I booted the cdrom with "linux noapic" and
successfully installed and ran 8.0.93.
I am ading arjanv to the cc list since that seems to be who get assigned kernel
stuff. Please adjust the cc list as appropriate or make this a dup of something
that I missed in my searches.
the apic stuff has been removed since a few days; that should fix this too.
I hope just from the install (BOOT) kernel since it seems to work fine when I am
running the smp kernel.
I have not tested it yet but how about the regular non-smp kernel. Would
running it with APIC enabled screw things up? If so then maybe it should only
be enabled for the smp kernel.
You comment about APIC being removed a few days ago. I have not tried one of
the more recent kernels but it is enabled for the 2.4.20-2.24 smp kernel (the
one that does not have the shutdown problem).
yes I meant the BOOT kernel. SMP kernel of course still has apic (no SMP system
without apics exist).
It's removed in -2.27 or so.. -2.30 has the reboot problem fixed fwiw
