next in thread | raw e-mail | index | archive | help
I got a panic while reading from a CDROM. A simple command such as
"dd if=/cdrom/packages/printing/mltex-3.1415.tgz of=/dev/null" will
cause a panic reliably.
I moved the CDROM drive from the Adaptec 2940UW to NCR 53c825 today,
and the panic happened after that. But then, I haven't been using the
CDROM for anything else than playing audio CD's for a while, so this
may just be a coincidence.
