Description Ernst Verhaar 2006-02-28 21:11:55 UTC

System freezes, on TTY10 I can see an Kernel BUG error. The routing still works (machine is used as a gateway), I cannot log in anymore via SSH orr TTY's. Looks like a deadlock.

Kernel BUG at drivers/block/ll_rw_blk.c:3060!

System Information:
3Ware Raid Controller 8006 SATA
2 * 200GB
Intel Xeon 2.0Ghz
Asus Mobo
OpenSuse Linux 10.0
Kernel 2.6.13-15.8-smp

No information is written to the log files. Probably because the last normal log is: Warning: 3w-xxxx ATA port Timeout

Could this problem be related to the 3Ware kernel modules?

Comment 1 Greg Kroah-Hartman 2006-03-02 03:21:48 UTC

What 3Ware kernel modules?  Did they come with the 10.0 kernel, or did
you get them from somewhere else?

Ok, I was kind of confused. Greg, you are correct. There are no kernel modules running for the 3Ware Escalade controller. I had a similar problem with kernel modules for an Areca Card. Therefore I assumed this also was a module. It is a device driver. 

From boot.msg
Inspecting /boot/System.map-2.6.13-15.8-smp
Loaded 24964 symbols from /boot/System.map-2.6.13-15.8-smp.
Symbols match kernel version 2.6.13.
No module symbols loaded - kernel modules not enabled.

Additional Information:

System just crashed again. I was transferring huge amounts of data to the raid array. This time no information visible. Screens wouldn't activate...

Comment 4 Ernst Verhaar 2006-03-02 21:26:43 UTC

And another crash. This time in kernel BUG at mm/rmap.c:493
I attached the logs below. But it now sounds as an hardware problem. 
Please confirm,

Kind regards,

Ernst

This is against SL10.0.  In order for us to debug things, we'll need a report against the 10.1 beta kernels.

Comment 7 Ernst Verhaar 2006-03-06 11:28:12 UTC

It seems that although new hard ware was used, there still was an error. With a KnoppixLive CD i got the same results. I am now trying to test the different hard ware for error.

My apologies.
