Subject: as_arq scheduler alloc with 2.6.0-test8-mm1
Date: Sun, 26 Oct 2003 01:54:27 -0800 (PST) [thread overview]
Message-ID: <20031026095427.23976.qmail@web13005.mail.yahoo.com> (raw)
Hi,
I am using 2.6.0-test8-mm1 kernel. I am using qlogic
driver patch with
this kernel. Every time I insert qlogic driver my
as_arq pool size
increases by 2000 objects of each size 76 bytes. I
have kgdb setup and I
tried to put break point in various function in
as_iosched.c to see if I
can see where it is getting allocated, but It never
hit the breakpoint.
Can anyone tell me whether its as-i/o scheduler
problem or something in
qlogic driver? How do I debug is problem?
After doing just insmod/rmmod for 20/30 times my
machine runs out of
free pages. If I dont try to insert qlogic driver my
system runs fine for
days without any problem. Following is the output of
/proc/slabinfo for
as_arq after doing insmod/rmmod.
Any help as to how to debug this problem is
appreciated.
Thanks
Amit
