Kernel tainted

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.

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

Thanks.

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

How do you all troubleshoot the error reported on irq 14 and 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…
