I CVSUP'ed and built yesterday, and am still seeing the same behavior; to wit: PC164/433, latest SRM runs fine as long as I do not try to use it for serial IO, namely multilink PPP via sio1 & 2. As soon as I do, the machine WILL freeze completely in a random (short) amount of of time. Config: PC164/433, 128MB, booting off IDE. FreeBSD 4.0-STABLE#12, cvsup'ed 000326. Using serial console on sio0, built in serial port with external modem on sio1, ISA modem on sio2. Linksys Ethernet card. This behavior replicates exactly on an Alphastation 400 4/233 using SCSI, same CVSUP, so it's not caused by the hardware config on either machine; the only things they have in common are the CPU type and the two modems I am using. I successfully use FreeBSD 3.4 stable on Intel with the same two modems to accomplish the same task. Any ideas?
