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.

esp causing crashes..
[mike -- included you for refs only] recently I started to dive into a problem that causes 2.2.x and 2.4.x to crash at shutdown and when minicom/mgetty is used. e.g. shutdown almost always crashed the system; if a fax is received, 3 out of 4 faxes ok, but also crashes system. I tried to contact the author of the hayes esp also but he seems to be pretty busy... Initially I thought that killall5, mike's product, somehow caused the mentioned crash but diving deeper into it I found that killall5 tries to kill mgetty -- and crashes the system. I tried a source version as well. same stuff (I use suse 7.0) I then tried without mgetty -- shutdown ok. Then I looked at esp.o as it's being used with mgetty -- now used minicom... that crashes most of the time when I exit the program. most of the time, it only crashes if you reset the modem connected. I trouble shooted further and disconnecting the plug of the esp and at the reconnect -- crash. It seems that somewhere in the esp code, something causes this particular weird crash. somehting like modem lines that get changed or so causing the crash ? 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. the system's a non OC dual SMP (BP6) but it happened on the old hardware (P5-100 w 64 MB) as well. are there any things I could do to truble shoot this further in order to use the esp again ? -- Grobbebol's Home | Don't give in to spammers. -o) http://www.xs4all.nl/~bengel | Use your real e-mail address /\ Linux 2.2.16 SMP 2x466MHz / 256 MB |on Usenet. _\_v - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
