Re: sata io freeze, 2.6.18 and also 2.6.24 [POSSIBLE SOLUTION]

[devzero]

hi luis, 

glad that it worked - but let us better call this a possible workaround, not a solution.

mind that you loose lots of performance with this, because all i/o is handled by the cpu now.

yes, please!

Re: sata io freeze, 2.6.18 and also 2.6.24 [the real culprit]

[Luis Sousa]

Hello,

I did as planned, and I dare to say now, with
relative certainty, that the reason I have had all
these instabilities, including application crashes,
sneaky corrupt backups, and the dreaded freezes
every other day was SMP and HyperThreading not working
properly. Booting with nosmp gives me a stable system.
Booting only with the sata-related arguments had
the system freeze overnight.

Sincerely,

Re: sata io freeze, 2.6.18 and also 2.6.24

[devzero]

did you try UP-kernel or tried booting with "nosmp" and does that make any difference ?

most likely this just "appears" as 2-way processor , but iŽm quite sure this is just a single-core CPU, but with HyperThreading enabled.

Hello,

I've been having consistent hard system freezes for a
long time, every 2 days or so, and finally decided to
move to the most recent stable kernel. Unfortunatelly
that didn't fix it. The freezes seem to be io-related;
they started since I moved my drive to sata. They seem
to happen mostly when there's an io-intensive operation,
like extracting a big archive; a reboot is needed.

Nothing ever shows up in the logs.

I'm using the following drive:

ATA device, with non-removable media
        Model Number:       MAXTOR STM3160215AS                     
        Serial Number:      6RA2TMJ4
        Firmware Revision:  3.AAD   

Linux localhost 2.6.24.4 #4 SMP Fri Mar 28 14:51:50 BRT 2008 i686 GNU/Linux

This is a 2-processor CPU:

# cat /proc/cpuinfo 
processor       : 0
vendor_id       : GenuineIntel
cpu family      : 15
model           : 4
model name      : Intel(R) Pentium(R) 4 CPU 3.00GHz
stepping        : 9
cpu MHz         : 3013.697
cache size      : 1024 KB

(same goes for processor : 1)

Sincerely,

Re: sata io freeze, 2.6.18 and also 2.6.24 [POSSIBLE SOLUTION]

[Luis Sousa]

Hello all,

Thanks to valuable help from roland, I was able to
boot with the following options:

``nosmp ide=nodma libata.dma=0''

after what I ran an agressive stability test for a
while, with no problem whatsoever. Maybe it's too
soon to say, but I have a good feeling this time. It
seems roland figured it out.

If everything goes well, I'll reduce the command line
in order to narrow the problem further down.

(and indeed, this is a hyper-threading single core CPU)
