hello!
公司部機行得好慢,下發覺原來冇set HDPARM
咁我用root行

引用:

# /sbin/hdparm -d1 /dev/hdc

/dev/hdc:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma    =  0 (off)

 


下面D lspci唔知關唔關事

有冇高手可以幫手?

linux新手上                                                                                                                                                                                                                       

部機長開,只一個月左右先restart, 咁都自己reset bios to default?
聽日去試下set反個bios先
個harddrive 係sata 但我估行legacy ide mode.

By the way, set錯bios會唔會抄左個Linux OS呀呢?

I meant, my system bios shouldn't reset to default. Since it's has an UPS. Unless there is a total power off one night.

But I will see tonight ;)

But our server is in datacenter :p
Maybe.....

1. system over heat -> reset -> bios reset
2. someone who share the same rack, unplug our server and put the power back on... and cause the bios reset.
3. my boss did it!                                                                                                                                                                                                                        

already in DMA mode  
maybe it's motherboard problem now? a consultant said it's possible south bridge problem.

                                                                                                                                                                                                                                                                               

Redhat 9.0 Linux version 2.4.20-8smp

Upgrade the kernel to 2.4.20.xxxxx still has same problem.
Run a live CD and the hard drive is at full speed.
So pretty sure it's software problem.
