Worked for me too, but didn't crash at IRQ2 - X just could not use the mouse.
Linux kernel (0.99.9) said it found a Logitech Busmouse no matter what IRQ it was at
(I removed the par./ser. I/O card and tried the mouse on IRQs 2-5 with kernel set to
default 5 - Linux always "found" it, but X only worked on IRQ 5 = kernel setting).
One slight problem for me though :-(
Linux (and MS-DOS Logitech driver) will work with the Mouse set to IRQ 2 (the Linux
kernel being configed for IRQ 9), but MS-Windows just freaks out completely!
Ocasionally I do need MS-Windows <yuck!>, so I have had to put the mouse back on
IRQ 5, which means no IRQ for /dev/lp2, which means dead slow printing compared to
/dev/lp1...
Wrong newsgroup, I know - But if anyone has any ideas about my MS-Win prob please mail!
Andrew.
P.S. Had the same problem when I configured my Adaptec 1542C for IRQ 14 (I was asking for
trouble! :-)
Linux and DOS had no problems, but MS-Windows 3.1 absolutely nuked my DOS partition's FAT!
I guess any Linux kernel that included IDE support would also barf...(?)
Have to look for those free IRQs elsewhere... How about COM4 on IRQ 14 instead of 12? :-)
