Summary: kernel crash during dbench against NFS
Product: openSUSE 11.0
Version: Final
Platform: x86-64
OS/Version: Linux
Status: NEW
Severity: Critical
Priority: P5 - None
Component: Basesystem
AssignedTo: bnc-team-screening@xxxxxxxxxxxxxxxxxxxxxx
ReportedBy: vmarsik@xxxxxxxxxx
QAContact: qa@xxxxxxx
Found By: System Test
Testcase:
- openSuSE 11.0 on x86_64
- local filesystem locally mounted over NFS
- dbench runs on the NFS share
On one machine with default settings, this crash occured in cca 50% of my
sequence runs (my sequence takes cca 6 hours).
On another machine I increased the kernel messages verbosity, and now it
crashes in cca 5% of the runs.
Crash details from serial console follow. After the crash, the system is in a
state when you cannot login anymore, and running processes do not respond to
anything that I tried; but one still gets ping responses.
Crash details:
Welcome to openSUSE 11.0 (X86-64) - Kernel 2.6.25.5-1.1-default (ttyS0).
