Yes, serial_cs is claiming that we don't have a device associated with the port, so we're treating it as a legacy port. However, serial_cs is implementing the suspend/resume methods. This is wrong, since that means the port will be suspended twice, and hence causes this bug. serial_cs needs to register the ports along with the PCMCIA device with which the port belongs to. This will stop it being treated as a legacy serial port. Unfortunately, it's too late tonight for me to dig into PCMCIA to work out how we get at the device structure - I can't find any examples off hand either. Therefore, it may be a while before I can produce a patch to resolve this. -- Russell King Linux kernel 2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of: 2.6 Serial core - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
