SMP kernel locks up when netscape window resized
Last modified: 2007-04-18 12:29:08 EDT
It seems that the SMP kernel installed on 7.0 locks up solid (even network
is off line) if the netscape window is resized. Both myself,
on an Abit BP6 with
128 MB ECC RAM,
IBM deskstar 20.5 GB disk (IDE) and
matrox G400 video card,
3com 10/100 NIC, with dual celeron 500's non-overclocked
and my colleague on a DELL server (all SCSI, I think 1 GB ram, 3com 10/100
hot swappable 72 GB drive, and all kinds of power suplies and fans) had the
I happen to run kde, but root might fire up in gnome by default. This is
for both of us. Also the kernel hangs when unattended (automatic power
Abit BP6 is not the stablest mobo in the world - I happen
to own a good one, but there are reports of unstable ones,
they apparently had a problem with a capacitor on one serie
of boards. Also the APIC to processor connection is marginal,
generating ocassional checksum errors.
1) Try to eliminate some possible problem sources -
if you are using AGP (is agpgart loaded?), DRI etc.,
turn it off, set some very basic X configuration
and try again.
2) Check in BIOS, whether your voltages are stable.
If the +-5V, 3V or processor ones (ca. 2V) jumps
more than a few hundreths of Volt, you have a problem.
3) Try running the kernel with "noapic" parameter - this
is known to help some people.
4) Alternatively try some of the 2.4.0-test kernel and
search for lines such as
Jan 4 16:08:52 trillian kernel: APIC error on CPU1: 00(04)
in the /var/log/messages. A few a day are unfortunately
normal for BP6, more is not OK.
FWIW: The netscape did not lock the kernel for me - Abit BP6,
128 MB non-ECC RAM, IDE IBM Deskstar 13.4 GB, 433 Celerons
overclocked to 506, Matrox G400, noname NE2000 card.
I used the 2.2.18 for a few days only, now I am running
2.4.0-test12 without problems.
