System: NetBSD mofo 1.6ZL NetBSD 1.6ZL (MOFO) #0: Fri Mar 26 22:30:29 EST 2004 grant@mofo:/data1/netbsd/current/src/sys/arch/i386/compile/MOFO i386
Architecture: i386
Machine: i386
>Description:
after upgrading my kernel to 1.6ZL, CD/DVD recording has become
impossible. running "cdrecord -v blah.iso" reports that the FIFO gets
emptied very soon after starting, and towards the middle of the burn
cdrecord aborts. the "buffer" figure always remains close to 100%.

turning on "burn-free" does not help.

booting a 1.6ZG kernel, the same command line for CDs and DVDs works
fine (FIFO and buffer staying close to 100%).

no idea where to start looking at this one .. maybe someone else has a
clue? ;)
