https://bugzilla.novell.com/show_bug.cgi?id=652954 https://bugzilla.novell.com/show_bug.cgi?id=652954#c0 Summary: serial/8250: Increase number of serial ports detected to 32 Classification: openSUSE Product: openSUSE 11.3 Version: Final Platform: All OS/Version: openSUSE 11.3 Status: NEW Severity: Enhancement Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: yegorslists@googlemail.com QAContact: qa@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.9.2.12) Gecko/20101026 Firefox/3.6.12 Both CONFIG_SERIAL_8250_NR_UARTS and CONFIG_SERIAL_8250_RUNTIME_UARTS should be increased to at least 32 in order to support multi port serial cards out of the box. This will cover at least the situation, where two 8 port cards are used simultaneously and there is still some room for internal ports or the other card. This bug report was created after initial discussion on the linux-serial mailings list: http://www.spinics.net/lists/linux-serial/msg03020.html Reproducible: Always Steps to Reproduce: 1. insert 8 port serial card based on 8250 UART family Actual Results: only some ports will be detected Expected Results: all 8 ports must be detected -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

So the system is working stable. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
