Hello!
Az egyik szerverben van egy (olcsó gagyi) pci sata vezérlõ (Silicon Image,
sii3512) és egy ideje feltûnõen lelassult a rajta lógó diszk (750G Samsung).
1-2MB/sec-ig leesik a sebesség. A logban az alábbiakat találtam. A kernel
valamiért szépen lépésenként PIO4 módig letekeri a sebességét!
Találkozott már valaki ilyennel ? Ötletek ?
Kernel: 2.6.18-6-sparc64-smp, Debian/Etch.
