I had a similar problem (intermittant) and narrowed it down to mod loading of
uhci-hcd so I blacklisted the module and loaded it later in rc.local where it
didn't hang.

Recently I tried unblacklisting it to see if it still hung and it did
not so you might try 2.6.13 final.

To narrow it down, edit rc.sysinit (depending on distribution) and make the
modprobes into modprobe -v

Hmm, above you say 2.6.13-rc[1-3]
???

Are these hangs temporary or permanent?  If they are temporary (ie: the
kernel recovers OK) then we should call them "stalls".  Because a "hang" is
considered to be a permanent state.

Either way, we need to know where the kernel is stuck.  Adding
`initcall_debug' to your kernel boot command may help.

And when the hang/stall occurs, hit the ALT-SSQRQ-P and ALT-SYSRQ-T key
combinations and send us the resulting traces.

Thanks.

Kernel 2.6.12 and 2.6.13 hangs for a while on boot

[Francisco Figueiredo Jr.]

Hi all,

I'm having little hangs while booting with kernels 2.6.12 and 2.6.13-rc1, rc2
and rc3.

It is strange that 2.6.12-rc1 booted ok without hangs.

I saw a post of Alan Cox on rc-1 release notes:

"Old ISA/VESA systems sometimes put tertiary IDE controllers at addresses
    0x1e8, 0x168, 0x1e0 or 0x160.  Linux thus probes these addresses on x86
    systems.  Unfortunately some PCI systems now use these addresses for other
    purposes which leads to users seeing minute plus hangs during boot or even
    crashes."

I thought this could be my problem, but it still hangs on boot.

Hangs appears just before mounting filesystems message and before configuring
system to use udev.

I'm using Gentoo with vanilla-sources. I already asked on gentoo lists and
nobody saw this behaviour. I tried google with no luck too. So my last resource
which could give me some light is here.

I'm using 2.6.13 on a Gateway laptop.

Do you know of something about this? Have you seen this problem?
Where could I look for more information about that in my system? I saw logs but
they don't say anything. Also, besides this hangs on boot, system seems to work
perfectly, but I'd like to remove this hangs from boot.

For while, I'm using 2.6.11.10 which is working ok.

Thanks in advance.
