Bug#507845: libc6: I am experiencing it too
Package: libc6
Followup-For: Bug #507845
Hi,
I am experiencing this bug on a Dedibox since its migration to Lenny
(on 2009-01-11). The server started to freeze randomly (2009-01-12,
2009-01-26, 2009-01-29) and is freezing once a day without anything in
the logs (at the time of the freeze that seems to be pure hardware
freeze) the last 4 days (2009-03-01, 2009-03-02, 2009-03-03 and
2009-03-04, the latter on new hardware).
I have asked for hardware replacement (yesterday, 2009-03-03), but it
still freezed today on the new hardware (same VIA C7 chips used by
Dedibox for its first generation Dedibox). Hence the problem shall be
triggered by the software...
# LANG=C dpkg -l libc6*
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Cfg-files/Unpacked/Failed-cfg/Half-inst/trig-aWait/Trig-pend

+++-==============-==============-============================================
ii libc6 2.7-18 GNU C Library: Shared libraries
pn libc6-i686 <none> (no description available)
un libc6.1 <none> (no description availabl
I have removed libc6-i686 only today (after the last freeze) upon
Aurélien's suggestion in this bug report (I will see if it changes
anything).
# uname -vomsr
Linux 2.6.26-1-686 #1 SMP Sat Jan 10 18:29:31 UTC 2009 i686 GNU/Linux
The only suspicious thing in the logs are such lines that happen
before the freeze (it might be unrelated):
In /var/log/messages:
Mar 3 23:24:12 metis kernel: [ 70.272030] Clocksource tsc unstable (delta = -92054101 ns)

(the freeze happened before 02:43).
Then after hard reboot (manually triggered around 08:57):
