On Linux 2.2.17 (Debian 2.2) the modem works fine but I had problems where attempts to use devices on my PCI SCSI card (BusLogic BT-958) froze the system, and playing audio CDs on the IDE CD-ROM drive got sense_key errors (both seemed to work swell in 2.4.5). Normally, the modem is at /dev/ttyS2, irq 5; with 2.4.5 it insists on calling it "ttyS04" (below) and it's unusable... when I try to use setserial to give the proper values to /dev/ttyS2, I get: "ttyS2: LSR safety check engaged!"; I tried making a /dev/ttyS4 device but that didn't work either... I popped out the ethernet card (D-Link DFE-530TX+) and the extra 2 USB ports but that didn't help; I'm back to 2.2.17 temporarily, just so I can have connectivity to send this mail. All the relevant info follows, I hope; I'd appreciate any advice or assistance with this ... >>From dmesg: ---------------------------------- PCI: PCI BIOS revision 2.10 entry at 0xf1150, last bus=1 PCI: Using configuration type 1 PCI: Probing PCI hardware Unknown bridge resource 0: assuming transparent PCI: Using IRQ router VIA [1106/0686] at 00:04.0 Found VT82C686A, not applying VIA latency patch. ...
