Q: I/O Problems with Linux 2.4.10 SMP on Tyan Tiger S2460 ?

Dear All,

I'm running a Tyan Tiger S2460 with two Athlon MP 1700+, using SuSE 7.3
2.4.10 SMP Kernel. In addition i have 2 Adaptec 29160, each serving at the
moment only one Seagate Cheetah disk. Creating with Oracle in parallel
4 datafiles each 1GB i come up with 34 MB/sec.

On my previous Gigabyte i440 BX with SCSI U2W onboard using above Linux
version and disk layout, i came up with 48 MB/sec.

So, where is the problem ?

Attached i have the dmesg command output. The only thing i can see is the

CPU has inconsistent mtrr settings

message. mtrr as a module is activated. Could this be the problem ? During
the run of the above creation of the datafiles, i get the expression only
cpu at a time works, but i do not know how to prove it.

Thanks for any help.

Ciao,
