Hi all,

I have a SLES 11SP3 with the following tainted code.

# cat /proc/sys/kernel/tainted

2147483650

Below is the error I saw from this server.  
[2.279063] libata version 3.00 loaded.  
[2.287286] ata\_piix 0000:00:07.1: version 2.13

[2.492882] Disabling lock debugging due to kernel taint

Does anyone encounter this issue? How do you all troubleshoot the error reported on irq 14 and irq 15?

Thanks.  
Li

Hi Li,

> [2.288698] ata2: PATA max UDMA/33 cmd 0x1f0 ctl 0x3f6 bmdma 0x1060 irq 14  
> [2.288835] ata3: PATA max UDMA/33 cmd 0x170 ctl 0x376 bmdma 0x1068 irq 15

I don’t recognize this as an error - to me it looks like a standard report about seeing a PATA disk each on ata2 and ata3, using irq 14 & 15, resp.

Do you experience any actual problem, are you worried about the root cause of the kernel taint or was it just those two device report messages?

Regards,  
Jens

Stepping out on a limb. My guess is that the VMware Virtual IDE CDROM driver  
isn’t exactly open source, thus the taint…
