Mailing List Archive: OOPS: ?in filp_open? on my console this morning

Hi All,
I left gnome-libs compiling when I went to bed last night. In the morning
this Oops was on the console, which I presume was from an overnight cron
job (RH 5.1 runs cron.daily at 04:02)

I've done some investigating and found that it's in some way connected to
the AHA-152x driver.
The oops can be triggered like this:
cd /proc/scsi/aha152x
ls
I did it a few times and now I don't get the oops, but the ls process
hangs. I have to use SAK to kill ls.
I tried doing "strace -o ~/strace.out ls" but no file was produced...
The driver carries on working - there is only one drive attached to that
controller, and it's used for news and swap. Both still work.
I'll cut the rest of my report except the oops itself.
Jon.
