regarding ali5451 problems that show up on kml, i just had access to
oliver's laptop which has the infamous ali5451.
both oss' trident and alsa's snd-ali5451 cannot
# modprobe snd-ali5451
PCI: Found IRQ 4 for device 00:08:0
URQ routing conflict for 00:08:0, have irq 5, want irq 4
then kernel cries:
hda: status timeout: status=0x80 { Busy }
hda: DMA disabled
hda: drive not ready for command.
disks cannot anymore be accessed. the system is still fine (no oops,
no freeze).
the vfs & ext3 then ended in I/O error since the disks answered
themselves busy to the eide controller.
the bugs ali5451 chips suffer may be related to :
- either the poor ressources allocation on laptios, which is poorer &
poorer since acpi "invade" laptops
- or driver misconception regarding irq sharing
the cars is "M5451 PCI South Bridge Audio" manufactured by Acer
Laboratories Inc. [ALi] (with pci ids : 0x10b9 0x5451)
irq 5 has been allocated to ali snd card, pcmcia cardbus controller
(managed by yenta_socket).
olivier <[EMAIL PROTECTED]> is the owner of that fscking
chip.
this is a compaq laptop.
i have access to another compaq laptop that works well with oss
trident. this is a compaq laptop too.
kernel is 2.4.18 based and alsa was tested with 0.9.0rc3 & rc5
