Thanks,
I finally got around to testing the above, but unfortunately it
doesn't fix the problem. Meanwhile I did configure savecore (the
default /var isn't large enough for the core files) and crashinfo
though, see attachments.
I send print jobs to my FreeBSD server from my Mac using cups on both
sides. The panic appears to be related to what I print, even though
that shouldn't matter at all at the driver-level.
The first document I printed was a large JPEG turned on its side and
printed alright, without a panic.
After that I printed page 106 from a PDF-version of the FreeBSD
handbook (section 3.2.6 Changing Console Video Modes) that I
downloaded at June 3rd this year and the below panic occurred.
The previous panic I posted about was also caused by a 1-page PDF
document.
Is there anything else I can provide to help fix this problem?
