Man I can't get this right. Third time I've tried to send this because my
from address keeps messing up. Finally got it to stick in there.
Problem 1, guide:
Can I turn off .15's OSD menu so M goes straight to the guide again?
Problem 2, DMA:
So I started getting random lockups pretty frequently a few days ago.
Seems to happen when nothings been recorded in a while and the system
starts to record. The error is almost always DMA related in
/var/log/messages:
May 28 11:42:56 myth kernel: hdd: timeout waiting for DMA
May 28 11:42:56 myth kernel: hdd: timeout waiting for DMA
May 28 11:42:56 myth kernel: hdd: (__ide_dma_test_irq) called while not
waiting
May 28 11:42:56 myth kernel: hdd: status error: status=0x7f { DriveReady

May 28 11:42:56 myth kernel: hdd: status error: error=0x7f {

May 28 11:42:56 myth kernel: hdc: DMA disabled
or
May 28 01:29:51 myth kernel: hdd: dma_timer_expiry: dma status == 0x61
That first error only shows it disabling dma on hdc, but it actually does
it on both drives. I've read a lot on disabling apic using noapic and
nolapic at boot time, but from my cat /proc/interrupts I see it's not
using apic (XT-PIC instead of IO-APIC) (nForce2 chipset):
0: 30907 XT-PIC timer
1: 6 XT-PIC keyboard
2: 0 XT-PIC cascade
4: 111 XT-PIC serial
5: 35391 XT-PIC nvidia
8: 1 XT-PIC rtc
9: 29648 XT-PIC ivtv: iTVC15/16 mpg2 encoder chip
11: 2577 XT-PIC eth0, NVIDIA nForce Audio
12: 58 XT-PIC PS/2 Mouse
14: 11432 XT-PIC ide0
15: 2990 XT-PIC ide1
NMI: 0
ERR: 123
I tried adding them anyway, and still get problems.
Also, I've noticed that the drive only uses udma2 instead of udma5 from
doing an hdparm -I. Should I try to enable udma5 (and how?)? I've just
tried lowering video res to 480x480 and dropping audio quality to try to
lower disk access.
Any other ideas would be helpful.
Thanks!
Ben
