Restart hangs on Toshiba Qosmio F20
Last modified: 2008-05-22 00:15:19 EDT
Description of problem:
Restart hangs on Qosmio F20.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. From "System" menu, select "Log Out" and "Restart".
System shuts down.
A "TIMER INTERRUPT ERROR" message appears at the top of the screen
Grub menu appears
System starts to boot in Fedora, but hangs, always at the same place. I will
post the last lines when I try the Restart again. I have to shut down by holding
the Power button, then I can restart normally.
Restart without any manual intervention
Restart works fine with other OS's, such as Knoppix 5.1.1, or Windows XP.
Last lines appearing on screen correspond to the following in the following
98 virtual kernel memory layout:
99 fixmap : 0xffc53000 - 0xfffff000 (3760 kB)
100 pkmap : 0xff800000 - 0xffc00000 (4096 kB)
101 vmalloc : 0xf8800000 - 0xff7fe000 ( 111 MB)
102 lowmem : 0xc0000000 - 0xf8000000 ( 896 MB)

104 .data : 0xc0636c47 - 0xc0759a44 (1163 kB)
105 .text : 0xc0400000 - 0xc0636c47 (2267 kB)
106 Checking if this processor honours the WP bit even in supervisor mode... Ok.
107 SLUB: Genslabs=22, HWalign=64, Order=0-1, MinObjects=4, CPUs=1, Nodes=1
Next lines in a normal dmesg are:
108 Calibrating delay using timer specific routine.. 3993.16 BogoMIPS
109 Security Framework v1.0.0 initialized
110 SELinux: Initializing.
111 SELinux: Starting in permissive mode
Presumably the system is hanging in the "Calibrating delay" line because of the
TIMER INTERRUPT ERROR.
Can you try the workarounds in section "System hangs on reboot":
Tried reboot=b, w, and b,w in grub.conf. System always hangs. This also happens
in mode 3 and 1 (i.e. I have added "1 reboot=r,w" to the end of the "kernel" line.
Will work down the Common Problems in more detail and report later.
Adding the following parameters makes the reboot sequence work:
nohz=off highres=off .
So, the complete grub entry I am using is:
title Fedora (2.6.23-0.224.rc9.git6.fc8)
kernel /vmlinuz-2.6.23-0.224.rc9.git6.fc8 ro root=LABEL=/ rhgb nohz=off
As you can see, I have updated the kernel since first reporting this bug.
I'm reviewing this bug as part of the kernel bug triage project, an attempt to
isolate current bugs in the Fedora kernel.
I am CC'ing myself to this bug and will try and assist you in resolving it if I can.
There hasn't been much activity on this bug for a while. Could you tell me if
you are still having problems with the latest kernel?
If the problem no longer exists then please close this bug or I'll do so in a
few days if there is no additional information lodged.
Still have the bug with kernel-22.214.171.124-107.fc8 .
Okay, thanks for the update. It might be worth testing with 2.6.24 when it
arrives and updating this bug.
Tried with kernel-126.96.36.199-12.fc8 that has just appeared. Looks ok, but I'd like
to test when bug https://bugzilla.redhat.com/show_bug.cgi?id=436589#c4 is
resolved, as losing the network is a show stopper for me.
Was able to warm-boot from kernel-188.8.131.52-137.fc8 to kernel-184.108.40.206-34.fc8
and within the latter, deleting the extra parameters I had added to the the line
in comment #4. Looks good, but networking must be started manually with the new
Works with kernel 220.127.116.11-18.fc9.i686 .
