Date: 24 Feb 2003 21:13:29 -0600 [thread overview]
Message-ID: <1046142808.24476.42.camel@tyan.crapulence.org> (raw)
Just another voice in the crowd...
TYAN 2462 dual 1200MP, and another w/ dual 1900MP
Dual WD100 IDE, seperate channels
Current BIOS 2.13
1GB RAM
I noticed this behavior when I started playing with 2.4.20 and could
never figger it out - went so far as to bring up KGDB and was way down
in the IDE DMA code, scary stuff... Kept scanning LKML and finally found
this gem of a thread...
Ran up a clean, fresh kernel from pre4-ac5, four combos
1) CONFIG_AMD_PM768=Y CONFIG_BLK_DEV_IDEDMA_PCI=y
2) CONFIG_AMD_PM768=m CONFIG_BLK_DEV_IDEDMA_PCI=y
3) CONFIG_AMD_PM768=Y CONFIG_BLK_DEV_IDEDMA_PCI is not set
4) CONFIG_AMD_PM768=m CONFIG_BLK_DEV_IDEDMA_PCI is not set
In cases 1 and 3, hang at boot, pressing the power button frees it up.
In cases 2 and 4, no boot hang, and, at lease for me, no hang when
amd76x_pm module's loaded
So, back to playing - if you need some testing on this board, let me
know - I use one at work and one at home, takes no time at all to gen up
and try things out, and they'll get pretty good exercise.
Regards,
Gio
