Subject: [2.4] siimage locks hard on high load
Date: Fri, 12 Sep 2003 13:44:43 +0200 [thread overview]
Message-ID: <200309121344.43573.adasi@kernel.pl> (raw)
I've got Asus a7n8x deluxe with on-board Silicon Image SATA and 2xBarracuda
120GB connected to it in software RAID array.
On high disk load (e.g. cp -Rf /usr/src/linux somewhere_else) kernel locks
hard after about 10 seconds (magic sysrq is not working).
It happens only when DMA is enabled.
/dev/hda:
multcount = 16 (on)
IO_support = 1 (32-bit)
unmaskirq = 1 (on)
using_dma = 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 16 (on)
geometry = 14593/255/63, sectors = 234441648, start = 0
Also, I'm not really satisfied with speed of this array:
/dev/md1:
Timing buffered disk reads: 64 MB in 1.77 seconds = 36.16 MB/sec
Any solutions/fixes?
