Re: smp hangs with 2.2.19 kernel

[kees]

Hi,

I'm too chasing this one. I have only one IDE drive and an SCSI controller
which is mostly idle but sometimes used for a scanner. At first I thought
is was hardware but I'm going to believe it is a software problem. 
I replaced most of the hardware even the motherboard.
2.2.19 with PIII-667 Mhz/128MB MSI 594D mobo.
