I tried a source version as well. > same stuff (I use suse 7.0) I dont like to be the sort of person who, when people report problems, fires back "it works fine here!"...but...just as a point of reference, I have a Hayes ESP too -- it's connected to a 56k modem. I havent had any crashes or hangs related to it, but I dont use mgetty. (I use rungetty, a variant of mingetty, for VC's). Seeing this, I will compile up mgetty here to see if I can replicate it. (once in a while, communications becomes non-responsive -- but I suspect that it's just my Zoom modem, which clams up for no apparent reason. The port seems to be doing it's thing.) > the IRQ is 11, not using DMA, IRQ is set to legacy in the BIOS. > it happens with any 2.2.xx version and also happens with 2.4.0. I'm running 2.4.0-ac12 here. ESP is set to 180h, IRQ 3, DMA 3. (I disabled my onboard serial ports). CPU is a classic Pentium. I've been running it w/ rx_timeout=1 (the minimum usable value, since it seems to give lower ping times) Got this ESP off eBay -- in fact, I got it after reading Mr. Jansen's recommendation 2 years ago in the comp.dcom.* groups (probably ISDN), noting how flexible and tweakable the ESP drivers are. FWIW, I was getting mountains of TCP errors before I got this card, and they all disappeared once I installed the ESP. It's an amazing card. -- Mark Orr markorr@intersurf.com - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
