Greetings,
I have recently run into some trouble trying to boot a custom configed
linux kernel with Adeos. During boot the system seems to have problems
with the SATA hard drives with messages like,
ata1: slow completion (cmd ef)
ATA: abnormal status 0x0FF
ata1: command 0x25 timeout, stat 0x50 host-stat 0x24
And then finally towards the end of the boot sequence, I get "ALERT!
/dev/sda3 does not exist. Dropping to a shell!"
I am using a highly modified config customized for this machine
(Highlights of the config: It excludes a lot of drivers, SMP build, and
both SATA-as-SCSI-driver and the regular PCI IDE driver are enabled.)
Unpatched this customized kernel works fine. And as expected, if I use a
more general config file (one that came with my distro) the Adeos
patched kernel boots normally. Its just the combination of Adeos and
customized config that seems to be the problem. Does anything jump out
at anyone? I have include my config file with this email.
What I-pipe patch version are you using?
Could you try with CONFIG_PCI_MSI disabled? There has been other reports
on MSI issues recently, maybe yours belong to the same group.
Thanks,
Jan
PS: Unrelated to the problem but maybe still interesting: If you plan to
use Adeos/I-pipe as a real-time enabler (e.g. with Xenomai), you should
switch off CONFIG_ACPI_PROCESSOR, CONFIG_CPU_FREQ, and CONFIG_APM.
Recent Xenomai versions should warn you about this fact as well.
That seems to have fixed the problem! The new kernel with this disabled
boots just fine. Thanks!
Well, I wouldn't say "fixed", it works around the bug.
By the way, I was using I-pipe patch 2.6.15-i386-1.3-07.
Philippe, any news on the MSI issue?
Nope. Unfortunately, now hw at hand that exhibits the issue, and no time
to dig it anyway.

I can't lend out hardware, but if there are specific tests or patches
you want me to try, by all means send them my way.
