According to the manufacturer, it is supported in kernel 2.6.12 Version-Release number of selected component (if applicable): kernel 2.6.9-34 How reproducible: Install serial card with dongle/break-out cable, install OS Steps to Reproduce: 1. Insert Hardware 2. Install RHEL 4 AS u3 x86_64 Actual results: Only 1 serial port is useable Expected results: All 8 ports should be useable Additional info: Customer (ITT Systems at Patrick Air Force Base) recompiled stock kernel with patch, included below, and the card worked. This was on a Dell PE 6850 w/ 4 Intel Xeons Here is some card related output: --- [root@dev-laps-svr2 ~]# dmesg|egrep -i "serial|sealevel" Serial: 8250/16550 driver $Revision: 1.90 $ 8 ports, IRQ sharing enabled [root@dev-laps-svr2 ~]# lspci|grep -i sealevel pcilib: Resource 5 in /sys/bus/pci/devices/0000:00:1f.1/resource has a 64-bit address, ignoring 0f:02.0 Serial controller: Sealevel Systems Inc: Unknown device 7804 (rev 01) --- Here is the official link: http://www.sealevel.com/ product_detail.asp?product_id=668&PCI_RS-232_RS-422_RS-485_Se rial_Interface_ Ultra COMM 8.PCI PCI RS-232, RS-422, RS-485 Serial Interface** ITEM# 7804

I agree with this patch (matches upstream).
Do we have the hardware to test here at Westford? If not, can someone tell us how to gain access to test?
any news on the acquisition of this hardware?
The customer had actually added this patch to the kernel while I was there in May. The card was recognized and all 8 ports were working.
