...ated on the same day. I had a panic that looks to me very similiar to the one described here (hence the subject): http://lists.freebsd.org/pipermail/freebsd-stable/2008-September/045405.html What caught my curiosity is the message: Unread portion of the kernel message buffer: acd0: WARNING - TEST_UNIT_READY read data overrun 18>0 kernel trap 12 with interrupts disabled I don't have atapicam built in the kernel and it wasn't loaded, and I'm pretty sure no media was inserted in my dvdrw unit since the last boot. The other report has a similar message too (acd1: WARNING - READ_TOC read...

...et, my server boots beyond the point of the previous pagefault, but runs in some serious trouble later in the boot process when trying to establish the data link. I''m seeing multiple errors like: ata1.00: qc timeout (cmd 0xec) ata1.00: failed to IDENTIFY (I/O error, err_mask=0x4) ata9.00: TEST_UNIT_READY failed (err_mask=0x5) and generally a lot of disk time outs. The server, not able to mount any root devices, later reverts to the initramfs. So basically besides the above mentioned CPU Panic, i got other issues with your changes which prevent a clear boot. Are there any prerequisites for your ch...

Thomas, Have spoken to Soren, from my bootlog he believes that the problem is in atapicam causing the system to lock up. He is happy to answer some questions but doesnt have time to delve into atapicam himself. Did you author atapicam, I have seen your name on the sourcecode, can you help me further? Whats next? Thanks Adam. -------------- next part -------------- An embedded message was
