Description of Problem: Supported card Xircom XBEM56G modem not accessible after installing RedHat Linux 7.1 on Dell Latitude CPx500HG laptop. Found 'serial_cb' referenced in '/etc/pcmcia/config' but driver not provided in 'kernel-pcmcia-cs-3.1.24-2'. Version-Release number of selected component (if applicable): kernel-pcmcia-cs-3.1.24-2 How Reproducible: Every time. Steps to Reproduce: 1. 2. 3. Actual Results: Find "serial_cb not found" log records in boot log messages. Module missing from /sbin/lsmod listing. Expected Results: No boot error messages and Module present in '/sbin/lsmod' listing. Additional Information: Found source code for 'serial_cb.c' in 'pcmcia-cs-3.1.24.tar.gz' on 'sourceforge.org'. Was able to compile the module and install it to enable access to the modem.
What kernel? The normal serial driver should handle cardbus stuff.
Typo: "XBEM56G" should read "CBEM56G". Formerly Used Kernel: 2.4.2 supplied with RedHat Linux 7.1 (Seawolf). Now Using Kernel 2.4.3 from 'kernel-2.4.3-12.i686.rpm'. Action: Renamed 'serial_cb.o' and removed reference in '/etc/pcmcia/config' for CBEM56G to find "normal" serial driver does indeed work as indicated. Comment: There are numerous references to 'serial_cb' in '/etc/pcmcia/config' for a number of different cards and RedHat should either supply the driver as configured or modify the configuration file as it did for the 'tulip_cb' driver references found in the standalone pcmcia distribution available from sourceforge.org upon which the 'kernel-pcmcia-cs-3.1.24-2.i386.rpm' is based. Failure to do so causes misleading error messages at pcmcia start-up time.
