When using either the unpatched 2.6.21_rc5 or SUSEs patched 2.6.21_rc6_git3-20070410174235 on a SUSE-10.2 x86_64 system the parallel port doesn't work right. If I "cat some_asciifile >/dev/lp0" the output on my Epson Stylus Color 880 is unreadable. "cat /dev/zero >/dev/lp0" creates random characters on the paper. Printing using cups also doesn't work any more. Switching back to SUSEs 2.6.18.8-0.1 kernel fixes the problem. Any Ideas, what might be broken here ?

Nope, but I have the same problem.
I'll dig into it some day, but it's not very high priority for me.

At some point that could be a problem, I have a shared printer on parallel (and replacing a printer for 11x17 work isn't cheap), as well as one PL/IP requirement, which is embedded in industrial machinery not likely to be upgraded.

Non-critical in the sense that I'm sure I can run old kernels for a decade if needed, but hopefully something to be fixed. Since there's no regressions list any more, I guess we will all have to complain about problems individually. :-(
