Subject: Re: [Oops] 2.6.10: PREEMPT SMP
Date: Tue, 8 Mar 2005 15:50:48 -0500 [thread overview]
Message-ID: <20050308205048.GC1546@monk> (raw)
Hello,
We have been experiencing a very similar oops on a Dell poweredge 2600, running Fedora Core 3 (FC3). This host is mainly used as a samba fileserver. The problem has been seen on 2 different machines (both Dell-pe-2600s).
The problem is only ever seen when running the SMP kernel in conjunction with samba.
We have been experiencing problems since early January when the samba/nfs/io load was increased considerably. Since then a number of 2.4 kernels have been used:
2.4.22.2115nptlsmp (FC1)
2.4.22-1.2199smp (FC1)
2.4.29 (vanilla kernel)
2.6.10-1.741_FC3smp (FC3)
2.6.10-1.766_FC3smp (FC3)
All 2.4 kernels produced the same result: full system lock-up, with no messages on the console or the log files.
The 2.6.10 kernel is giving an oops which has been seen 3 time in the last 3 days. A very similar one was seen pointing to eip: c01b2d98 on the 2.6.10-1.741 kernel.
I have included the kallsyms and System.map relevant to the instruction pointed to by the EIP. I can include the full files if required.
printing eip:
c01b387c
*pde = 2fcdd001
