Hi. I haven't seen any discussions about the 2.4.21-pre1 and pre2
kernels kernel panicing when you execute
/sbin/hdparm -d1 -c3 -m16 -k1 /dev/hdb
/sbin/hdparm -d1 -c3 -m16 -k1 /dev/hda
(where /dev/hda contains both my boot and root partitions).
I ran this command in a startup script to improve disk performance. It
would cause the kernel to panic on startup. I commented it out of the
script, and the newly built kernels would startup and run OK, but when I
went back and re-ran the script (with the now running system), it would
crash the box. I installed a new version of hdparm (5.3) to make sure
it wasn't an old version problem.
Thanks in advance, apologies if it's already been looked at, or if it's
just me.

Is this an oops that looks somewhat like (giving one line of context here):
Freeing unused kernel memory: 88 kbytes.
kernel BUG in header file at line 155
kernel BUG at panic.c:141
invalid operand 0000
CPU: 0
and then traces back with:
>>EIP; c01148df <__out_of_line_bug+f/20> <=====
Trace; c01a6ce7 <ide_build_sglist+127/160>
Trace; c01a738b <__ide_dma_read+2b/120>
...that's basically what I get with 2.4.21pre2, all drives on the legacy
IDE controller of an A7V333 and a PDC MBFastTrack133Lite RAID controller
configured in but no drives on it.
I'm doing some hdparms during bootup but I don't think it's getting to
them, I should add something to the top of the script to check, but I'd
rather not reboot the machine too often.
Apologies for the partial details of the oops, but my pen ran out. :-/
David.

Please provide controller and drive info and the call traceback
Ok. This is the oops (recorded with digital camera and re-typed in as
/var/log/messages et. al. had nothing). The controller is:
00:02.5 IDE interface: Silicon Integrated Systems [SiS] 5513 [IDE] (rev
d0)
The error message when I run /sbin/hdparm -d1 -c3 -m16 -k1 /dev/hdb
and /sbin/hdparm -d1 -c3 -m16 -k1 /dev/hda is:
IO_support = 3 (32-bit w/sync)
using_dma = 1 (on)
keepsettings = 1 (on)
