Not available since I swapped back to previous kernel (which is 5.2-CURRENT of Jan 13).
>Description:
cvsup'd the system to -CURRENT on Feb 2. Previous kernel build was with source as of Jan 13 2004 ; system is stable and happy with that build.
upon booting the new kernel the root mount failed due to the absence of ufs:/dev/aacd0s1a. the aac driver reported the following:
aac0: <Adaptec SCSI RAID 2410SA> mem 0xf0000000-0xf3ffffff irq 10 at device 1.0 on pci3
aac0: can't set up interrupt
device_probe_and_attach: aac0 attach returned 6
I rebooted the system using the previous kernel and everything was fine again.
I suspect the Jan 30 interrupt changes to aac may have upset something.
N.B. the only other device on the PCI3 bus is a display adaptor.
IRQ10 is also shared by Intel 82801EB (ICH5) USB controller and an Intel ICH5 SATA150 controller.
