Description Jan "Yenya" Kasprzak 2004-01-28 10:05:53 UTC

Distribution: Fedora Core 0.96 (x86-64)

Hardware Environment: Tyan Thunder K8S Pro (S2882), 3ware Escalade 7506-8,
4GB RAM, dual Opteron 244

Software Environment: Linux 2.6.1, 64-bit compiled.

Problem Description: The kernel does not boot when pci=noacpi option is in use.
It hangs during the 3ware card initialization - prints the following messages:

3w-xxxx: scsi0: UNIT #0: Command (000001002645b0) timed out, resetting card
3w-xxxx: scsi0: UNIT #0: Command (000001002645b0) timed out, resetting card

Then it tries the same with UNIT #1 (whatever it is, I have only one 3ware card
and only one RAID volume) and then the system locks up.

With acpi=off it boots correctly, as well as without pci=noacpi.

Kernel config and other possible details available on request.

please attach the dmesg and /proc/interrupts for the case where no boot flags are used. 
curious why pci=noacpi is being attempted if the system boots without it. 
 
thanks,

This seems to be fixed in 2.6.10-rc2 (did not check anything between).
