Comment 3 for bug 159260

To gather further information on this matter, I did try to perform the same task under Debian-Lenny, which is quite similar to Gusty (kernel 2.6.22-2, cups 1.3.2-1).
The only difference: Lenny does nor freeze, but collects thousands of missed RTC-IRQ's in the syslog. Printing via cups-lpd does not work either. The link between cups-lpd and cupsd seems broken. Here the relevant part of /var/log/messages:

pp:/home/ingo# tail /var/log/messages
Nov 12 12:17:25 pp cups-lpd[4155]: Connection from 192.168.0.21 (IPv4
192.168.0.21)

Nov 12 12:18:20 pp last message repeated 1211 times
Nov 12 12:18:20 pp syslogd 1.5.0#1: restart.
Nov 12 12:18:20 pp kernel: rtc: lost some interrupts at 1024Hz.
Nov 12 12:18:22 pp last message repeated 97 times
Nov 12 12:18:22 pp cups-lpd[4155]: Closing connection
Nov 12 12:18:22 pp kernel: rtc: lost some interrupts at 1024Hz.

So I maked the bug as 'affects Distribution.
