hi,
I noticed that the aha2940 driver can kill your system regardless of the kernel version. I tried with 1.2.13 and with 1.3.94 (I dont have 1.3.100 yet).
hardware layout is about:
+ asus sp3 board + i486/100 + 16MB real + 20MB swap + aha2940u (but same problem with plain aha2940) + ne2000 compatible card + 1G quantum fireball EIDE drive OR + very old 80MB drive + SCSI CD-Rom - this is the only device on the SCSI-Bus ! = Thosiba Quad-Speed.
how to crash:
type "dd if=/dev/scd0 of=/dev/null" switch to another VT, try to log in, do something like "ps" or "w" or "df" again, switch to another VT, try to log in, .... -"- [...]
when I used the 1G Quantum F.Ball, I got kernel panics, which I cannot report right now (the havent been saved to the logfile anyway...) after that, I switched to an old 80MB hd. with this drive I didn't get kernel panics anymore, but instead messages like "ide0 { irq timeout } " "ide0 { Reset complete } " and such. the system was in a slightly unusable state after that, e.g. I found /etc/passwd to be a hardlink to /usr/bin/loadkeys :-)
my conclusion is that there is a) a misbehaviour in the aha2940 code, which causes this "uncooperativeness" and b) a possible error in the ide code as well. shouldn't a "Reset complete" result in a continuing of the previous operations without confusing i-nodes ?
btw - I'm curious if someone else with a likely configuration can reproduce this error.
