Bug 89168
Summary: | Kernel 2.4.18-27.7 correctly autoconfigures SIIG 4-port RS-232 PCI SuperSerial card (PCI Class 0700: 131f:2052) with 4 16850 UARTS, but card only operates if setserial uart 16550 used; same card worked fine with kernel 7.0 (2.2.16-22). | ||

I've now reproduced this problem with 2 boards, which both have the same PCI ID: Class 0700 131f:2052 : 1. The older SIIG board, the `SuperSerial PCI 850' which actually has 4 real XR16C850's on it, 2 on-board DB9 connectors, and 2 extended DB9 connectors ( SIIG model #IO1866, SN #J6P010000400 ) 2. The replacement board, the `Quartet Serial 850 PCI', which has 1 on-board DB-25 connector and a 4-DB9 octopus (quadrapus? :-) cable that connects to it. ( SIIG model #IO873 SN #J6N020001839 ) Linux reports both boards as being the `Siig Inc CyberSerial (4-port) 16850' Neither board can transfer packets larger than 160 bytes through a port on Linux 7.3 when the ports are configured as 16850's, but can when configured as 16550's; on Linux 7.0, both boards transfer large packets (eg 1500 bytes) with better performance than on Linux 7.3. Linux actually put the ports on TTY lines ttyS4, ttyS5, ttyS6 and ttyS7 above. Thanks for the bug report. However, Red Hat no longer maintains this version of the product. Please upgrade to the latest version and open a new bug if the problem persists. The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, and if you believe this bug is interesting to them, please report the problem in the bug tracker at: http://bugzilla.fedora.us/ |
