It seams ok to copy or cat the file, but panic when browse the file from apache.
Apache use sendfile() to read the file
[pid 3536] read(10, "GET /Fedora/core/updates/6/i386/"..., 8000) = 513
[pid 3536] gettimeofday({1162347890, 56510}, NULL) = 0
[pid 3536] stat64("/opt/wwwroot/html/Fedora/core/updates/6/i386/repodata/repomd.xml",
{st_mode=S_IFREG|0644, st_size=1197, ...}) = 0
[pid 3536] open("/opt/wwwroot/html/Fedora/core/updates/6/i386/repodata/repomd.xml",
O_RDONLY|O_LARGEFILE) = 12
[pid 3536] setsockopt(10, SOL_TCP, TCP_CORK, [1], 4) = 0
[pid 3536] writev(10, [{"HTTP/1.1 200 OK\r\nDate: Wed, 01 N"...,

Hi, all
I try reiser4 and got a kernel panic.
I use kernel 2.6.19-rc3-mm1, config kernel to enable reiser4,
then I use reiser4progs-1.0.5 to excute following command,
mkfs.reiser4 /dev/hda5
mount -t reiser4 /dev/hda5 /hda5
cd /hda5
mkdir FC6_mirror
nohup wget -m -np -nH --cut-dirs=3 -R *-debuginfo-*
ftp://ftp.nara.wide.ad.jp/pub/Linux/fedora/core/updates/6/i386/ &
nohup wget -m -np -nH --cut-dirs=3 -R *-debuginfo-*
ftp://ftp.kddilabs.jp/Linux/packages/fedora/core/updates/6/x86_64/ &
then I make a link at $wwwroot/html/Fedora to /hda5/FC6_mirror
my web server is apache 2.2.3, use worker mpm,
when I use web browser to access the Fedora mirror
http://<myip>/Fedora/core/update/6/i386/
download the rpm files if fine.
until I try to access one file
http://<myip>/Fedora/core/update/6/i386/repodata/repomd.xml
the kernel panic.
this file's size is 1197 bytes, a common file.
the infomation print on the screen is something like :
kernel panic, at reiser4/plugin/item/tail.c:426
I reformat the partition and try again, the bug can reproduced.
any idea?
Best regards!
