[hard hang - HD LED on solid, machine locked up, should show p1 p2 p3]


This is a brand new mobo w/ an Opteron 148 on it.  SK8V.  The Gentoo 
LiveCD is a 2.6.5 kernel and it boots ok on it.  I'm starting to do 
tests to see what I can do to get it to function.

What I know at present.

1) Hard hang requiring reset switch
2) no known boot options affect it
3) no BIOS twiddling affects it, dma on/off, 32bit, whatever.
4) no generic or !generic IDE CONFIG_ options make a difference.

gcc version 3.3.3 20040412 (Gentoo Linux 3.3.3-r5, ssp-3.3-7, pie-8.7.5.3)

Can you try booting with "noapic" and/or "acpi=off"?

If it doesn't work, please do binary search to
check what is the last working kernel version.

Re: [boot hang] 2.6.7-rc2, VIA VT8237

[David Ford]

neither of these two options affect the outcome and the only known 
kernel that works on this are the Gentoo 2004.1 LiveCD (2.6.5 gentoo 
built) kernels.  I can't get a vanilla kernel to work on here.  I'm 
trying repeated versions and stripping everything possible out of the 
builds.  So far no luck.

Both 2.6.5 and 2.6.7 will boot using the GENERIC IDE driver.  I haven't 
yet gotten any kernel to not lock up using the VIA driver.

On another note, I can't get ANY network card to work in this machine 
other than with the gentoo LiveCD;  tulip, 3com, RTL, eepro, smc..

The e100 driver even gives me this nonsense: "SIOCSIFFLAGS: Connection 
timed out" when setting the interface up.

The eepro100 driver says it can't initialize the 82557 and check that 
the card is in a bus-master capable slot.  Self test failed.

This is silly.  The same hardware all works with the LiveCD kernel, no 
boot options.

Culprit found.  If CONFIG_IOMMU_DEBUG is enabled, the machine will hang 
on boot at the partition check when using the VIA driver.

The real culprit is buggy VIA silicon. Use this patch.

Yep, that patch makes this thing bootable now :)

Thank you,
