Subject: DMA problems with 3+ Promise IDE controllers
Date: Thu, 23 Dec 2004 21:26:27 +0200 [thread overview]
Message-ID: <41CB1BE3.465BD490@netgroup.co.za> (raw)
Hi,
I am curios if DMA bursting on the Promise cards are enabled by default
on
2.6.x kernels.
CONFIG_PDC202XX_BURST exists for the old PDC driver, but there seems
to be no similar option for the PDC202XX_NEW driver.
The problem I have is that I start to experience DMA errors as soon
as I plug in a third Promise PDC20268 Ultra 100/TX2 card into one
of my boxes. The system runs fine with only two cards, but as soon
as the third card is connected and drives attached to it, the following
errors are generated:
kernel: hde: max request size: 1024KiB
kernel: hde: 390721968 sectors (200049 MB) w/8192KiB Cache,
CHS=24321/255/63, UD

}

These errors are causing havok in my RAID5 setup.

Any idea how I could get all three cards to work in UDMA100 mode?
Help will as always be greatly appreciated
