Hi all,
the recent change made on sys/pci/if_xl.c(from the C source:
src/sys/pci/if_xl.c,v 1.72.2.5 2001/05/31 22:09:53 wpaul) seems
to make my system panic under moderate network load, like
downloading a 20MB+ file from a server on the local LAN. I backed
out the change (basically copying the old if_xl.c from 4.3-RELEASE)
and the system is now rock solid again. The panic is easily
reproducible, but the most weird thing is that I didn't get only
panics, but occasional hard lock-ups and also random cache
corruptions; for example, few times it corrupted the in RAM cached
libc, so all freshly started dynamically linked executables
cored.
The diff is not very large, since it includes only these three lines:
+ /* increase packet size to allow reception of 802.1q or ISL packets */
+ if (sc->xl_type == XL_TYPE_905B)
+ CSR_WRITE_2(sc, XL_W3_MAXPKTSIZE, XL_PACKET_SIZE);
What is this supposed to do other than panicing my machine? :)
I have these options enabled, but I don't think they are the culprits:
loader.conf:
hw.ata.wc="1"
hw.ata.tags="1"
hw.ata.atapi_dma="1"
sysctl:
vfs.vmdirioenable=1
This is a backtrace of the kernel panic and below it you can find
my dmesg output:
