Description Michael Lange 2010-11-19 15:23:38 UTC

i can't boot from latest livecd (autobuild) because i get a kernel oops with via_init_one failure
my mainboard has a "VIA VT6415" chip connected to the ide-cdrom with the install-cd 
the install-cd use the kernel 2.6.34-gentoo-r12
so i found this on http://www.kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.35-git11.log

    via82cxxx: fix typo for VT6415 PCIE PATA IDE Host Controller support.
    
    Without this fix, init of the via82cxxx driver causes a oops with a
    stack resembling the one below, and the boot blocks between init of
    USB devices and launch of init (was easy to bisect by booting with
    init=/bin/sh).

@kernel:

Any chance of getting a backport of this to the 2.6.34 kernel series or when do you expect us to have a stable 2.6.35 or later kernel marked stable?

Actually we already have a stable 2.6.35 kernel for x86 and amd64 should be done soon.

As we got new kernel versions marked stable, I expect this to be fixed.
Feel free to reopen the bug if you hit this again.
