Folks, 2.6.8-rc4-mm1 panics when booting (aic7xxx) with lots of SCSI ABORT and sens code errors. IDE ports give also failed probe messages. This is on AMD/nForce2 based system under Slackware 10.0 with 2.6.8-rc4-mm1 kernel compiled using GCC 3.3.4. Last kernel that worked was 2.6.8-rc3-mm1. The 2.6.8-rc3-mm2 flag pci=routeirq which Andrew suggested works and boots this kernel. Below is the full dmesg/lspci output. Thanks, Paul -- FreeBSD the Power to Serve!
