I cvsuped and built a new world and kernel yesterday at approximately 11:00 EST, 16:00 GMT. During reboot to the new kernel, it hung on the CD drive with a DVD in it. I think it has done that with earlier kernels too, but I don't often have a disk in the drive. I tried again with an audio CD in the drive and it also hung. I manually wrote down the verbose dmesg about the hang but left it at home this morning. It boots just fine without disk in the drive. I didn't have a data disk within reach and didn't test that combination. Today I tried to burn a 5.2-RELEASE ISO so I can test the ida controller in one of my Compaq 1850Rs. I see the same (I think) dmesg output and the burncd process is hung waiting for disk io. acd0: TIMEOUT - WRITE_BIG retrying (2 retries left) ata1: reiniting channel .. ata1: reset tp1 mask=03 ostat0=50 ostat1=01 acd0: stat=0x00 err=0x01 lsb=0x14 msb=0xeb ata1-slave: stat=0x01 err=0x04 lsb=0x00 msb=0x00 ata1: reset tp2 mask=03 stat0=00 stat1=01 devices=0x4<ATAPI_MASTER> ata1: resetting done .. acd0: pio=0x0c wdma=0x22 udma=0xffffffff cable=40pin acd0: setting PIO4 on AcerLabs Aladdin chip acd0: setting WDMA2 on AcerLabs Aladdin chip acd0: setting WDMA2 on AcerLabs Aladdin chip ata1: device config done .. acd0: WARNING - WRITE_BIG interrupt was seen but timeout fired acd0: WARNING - WRITE_BIG interrupt was seen but taskqueue stalled To my memory, that is exactly the output that I got when booting with a DVD in the drive with the exception that of "sed 's/WRITE_BIG/READ_BIG/g'". With the audio disk, I think it was READ_CD but I'm not sure exactly. This is a Compaq Presario 2195us.

I was in a hurry both times. Those are the only two times I've shutdown with this new kernel. -- Scott Lambert KC5MLE Unix SysAdmin lambert@lambertfam.org
