2.6.7-rc1-mm1: libata flooding my log

Hi,

I noticed following messages appearing very often in my log:

Any idea of what is going on? Is dmesg output needed? The system seesm to behave rel normal, beside a bit performance degration, I think.

BTW, the new libata version does two good things:
- write back is activated
- now hdparm -t /dev/sda gives high throughoutput straight form the first time.

Cheers,

Prakash

Reading REPORTING-BUGS for the info that is needed.

I wonder if you have a bad SATA cable, initially, though.

this is cosmetic, it was always activated.

this is because Andrew Morton fixed a bug unrelated to libata :)

Oh OK, so here it goes (I have rebooted to a patched mm kernel, but tha plain mm showed the same behaviour, just in cae you are wondering...):

I don't think so, because previous mm kernels didn't show anything like this.

bye,

Prakash

I tried again a 2.6.6 based mm kernel and all is OK. Furthermore I am not the only one getting these messages with the 2.6.7-rcX mm kernels. Any idea? I tried to copy the older libata to the new kernel, but didn't work as I got a compilation failure...

Prakash

So I tried something new. I enabled the SCSI error reporting and now get this:

FAILED
status = 1, message = 00, host = 0, driver = 08
Current sd: sense key Illegal Request
Additional sense: Invalid command operation code
FAILED

I found another interesting thing: It seems those errors only appear when I use mozilla thunderbird! Any idea what tb is trying to do to the hd? As I said earlier kernels didn't report such errors. (Are those actually errors?)

Prakash

I'm having similar problems (posted to linux-ide last week). Its not just thunderbird though, I can easily reproduce this under heavy disk activity (e.g. rsync'ing lots of data with a local server while unpacking/patching a kernel).

Daniel

I seems 2.6.7-rc2-mm2 fixed the issue. At least since 2h no entry in my logs. Well done, Jeff (if it was you :-)).
