sparc64 2.6 SMP RED state exception

2006-04-07 Thread Blars Blarson 

I've submitted bug 361214 about the frequent sparc SMP crashes with 2.6
kernels.

Is anyone running a sparc 2.6 SMP kernel and NOT having the system
crash under heavy disk I/O?  Please let the bug know if you have any
additional information.

With Microsoft, failure is not an option.  It is a standard feature.

	I use a sparc64 SMP kernel on my U60 (and on my U420) without any 
trouble. Kernel is official kernel (not from debian tree):
Linux bohr 2.6.15.6 #1 SMP PREEMPT Fri Mar 10 23:27:31 CET 2006 sparc64 
GNU/Linux


	I don't have any trouble with sparc64 architecture, only with 2.6 and 
sparc32 :-( Maybe this bug come from the same location than the bug I 
have submitted in bugzilla.kernel.org (#6344)... DMA mistake that only 
occurs with heavy disk I/O...

JKB

We have found that some systems are fine with later 2.6 kernels (say, in
the 2.6.15 series) and some are not.  sparc32 systems are a problem;
U1/U2 systems routinely crash under heavy disk I/O, U60 now seem fine,
SB1000 is fine, I think U5/U10 are OK, and so on.

Wouldn't it be good to also post this issue on the sparc kernel list: 
sparclinux_at_vger.kernel.org?
