[Oracleasm-devel] kernel BUG at include/asm/spinlock.h:146!

[Han Xie]

Hi,

I have a 3 node cluster on Firewire, and got this kernel BUG in the /var/log/messages file.  It seems suggest Oracle ASM introduces a kernel bug.  Is this true?  After this error, my cluster failed miserably.

The environment is: Redhat AS 4 kernel 2.6.9-11 ELsmp

ASM installed: oracleasm-2.6.9-11.ELsmp-2.0.0-1
		oracleasmlib-2.0.0-1
		oracleasm-support-2.0.0-1

Firewire rpm installed: oracle-firewire-modules-2.6.9-11.ELsmp-1286-1

Here is the full text of the error in the /var/log/messages:
