Description of problem: Harmless, but repeatable "general protection fault" messages appear in dmesg while transferring a file Version-Release number of selected component (if applicable): kernel-2.6.29-16.fc11.x86_64 How reproducible: Quite rare, but happened multiple times, and again after a reboot Steps to Reproduce: 1. Take any Amiga equipped with NetBSD 1.4 from your collection 2. mount linuxhost:/arc /arc 3. copy over one huge 4GB file with dd 4. sit back for a few hours Actual results: GPF messages creep every hour or two Expected results: Things should go smoothly Additional info: dhclient-script used greatest stack depth: 3112 bytes left JBD: barrier-based sync failed on dm-2:8 - disabling barriers type=1400 audit(1238365767.786:16035): avc: denied { read } for pid=15364 comm="sshd" name="home" dev=sda1 ino=13 scontext=system_u:system_r:sshd_t:s0-s0:c0.c1023 tcontext=system_u:object_r:default_t:s0 tclass=lnk_file general protection fault: 0000 [#1] SMP last sysfs file: /sys/devices/virtual/net/pan0/statistics/collisions CPU 0 Modules linked in: affs nfsd lockd nfs_acl exportfs rpcsec_gss_krb5 auth_rpcgss des_generic sunrpc fuse rfcomm bridge stp llc bnep sco l2cap coretemp hwmon_vid ipv6 nf_nat_irc nf_nat_ftp nf_conntrack_ftp nf_conntrack_irc ipt_ULOG xt_TCPMSS iptable_mangle iptable_nat nf_nat cpufreq_ondemand acpi_cpufreq freq_table kvm_intel kvm uinput pcspkr firewire_ohci firewire_core iTCO_wdt i2c_i801 crc_itu_t skge iTCO_vendor_support snd_hda_codec_realtek atl1 snd_hda_intel mii snd_hda_codec pata_jmicron snd_hwdep snd_pcm snd_timer snd soundcore snd_page_alloc btusb bluetooth asus_atk0110 hwmon ata_generic pata_acpi ext4 jbd2 crc16 radeon drm i2c_algo_bit i2c_core [last unloaded: scsi_wait_scan] Pid: 6019, comm: nfsd Tainted: G W 2.6.29-16.fc11.x86_64 #1 P5K RIP: 0010:[<ffffffff8116b266>] [<ffffffff8116b266>] inode_has_perm+0x30/0x66 RSP: 0018:ffff880106d05c50 EFLAGS: 00010246 RAX: 6b6b6b6b6b6b6b6b RBX: 0000000000100004 RCX: 0000000000000000 RDX: 0000000000100004 RSI: ffff88008f11b4b0 RDI: ffff88010a04d300 RBP: ffff880106d05ca0 R08: 0000000000000000 R09: ffff8800331e27b0 R10: ffff88011418ae70 R11: 0000000000000000 R12: ffff88008f11b4b0 R13: ffff88010a04d300 R14: ffff88010d012c00 R15: ffff88008f11b4b0 FS: 0000000000000000(0000) GS:ffffffff8197d000(0000) knlGS:0000000000000000 CS: 0010 DS: 0018 ES: 0018 CR0: 000000008005003b CR2: 00007fd59372a000 CR3: 0000000056ef0000 CR4: 00000000000026e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process nfsd (pid: 6019, threadinfo ffff880106d04000, task ffff8801121723c0) Stack: 0000000000000000 0000000000000246 ffffffff8160cc18 0000000000000246 ffff880106d05c90 ffffffff811a2e67 ffff8800331e27b0 ffffffff8160cc00 ffff880106d05cb0 ffffffff81398d01 ffff880106d05cd0 ffffffff8116e444 Call Trace: [<ffffffff811a2e67>] ?

It appears so... It this happening on more recent kernels?
Sorry, at this time I can't reproduce it because I've left my pile of NetBSD/m68k Amigas in Italy. If the traceback I provided does not immediately ring any bell, I guess we can close this report as INSUFFICIENT_DATA or CANTFIX.
I agree.. we can always re-open it...
