Hardware:
Athlon XP 1600+
Epox 8KHA+ VIA KT266A
BT878 TV-card (bttv card=36, tuner type=1)
Edimax Via6302 4port PCI Usb2 controller (ehci-hcd)
Lacie P3 250GB Usb2 hard drive (usb-storage, reiserfs)
Edimax Gigabit Ethernet (r8169)
I recently updated my machine with pci usb2 controller and usb2 hard
drive. I have been running the same machine on 2.4 kernels for a long
time and it has never had stability issues.
I decided to upgrade to kernel version 2.6.6 since i couldn't get
usb2 controller to work in 2.4.26, and also realtek gigabit ethernet
driver in 2.4.26 causes hangs.
Soon after i updated i noticed problems whenever bttv, usb2 hard drive
and nfs/GigE were used together at high loads. First of all, usb2
throughput was disappointing, i only got about 8MB/s while the
manufacturer claims sustained datarate of 35MB/s.
I tried to stresstest the drivers by launching TvTime (which uses bttv),
listening to mp3s, and at the same time transferring data to and from
usb2 hdd and nfs partitions on another machine.
Problems while transferring data from usb2 hdd:
- TV picture has weird artifacts
- Constant clicks and snaps from mp3 player
- NFS will hang for about 10sec every now and then
- And finally after a few minutes the machine either hangs completely
or the usb-storage and ehci drivers freeze and the usb2 hdd isn't
accessible before the machine is rebooted.
The other machine i have is kt600 athlonxp with just ide hard drives
and the gigabit ethernet nic, it is also running kernel 2.6.6 and
it has been completely stable so far.
Here's a clip from syslog:
