Namely, if a reiserfs partition is mounted with "-o acl", any attempt to create a file on it results in an Oops similar to this one: Unable to handle kernel paging request at fffffffffffffff3 RIP: {reiserfs_cache_default_acl+164} PML4 103027 PGD 170a067 PMD 0 Oops: 0002 [1] CPU 0 Modules linked in: usbserial parport_pc lp parport joydev sg sd_mod sr_mod scsi_mod cpufreq_userspace powernow_k8 thermal processor fan snd_d Pid: 18656, comm: kdm Not tainted 2.6.9-rc1-mm5 RIP: 0010:[] {reiserfs_cache_default_acl+164} RSP: 0018:00000100143b3db8 EFLAGS: 00010286 RAX: 0000000000000001 RBX: 0000000000000001 RCX: 0000000000000002 RDX: 000001001bf3cc68 RSI: ffffffff804272c0 RDI: 000001001bf3cc30 RBP: 000001001bf3cc78 R08: 0000000000000000 R09: 0000000000000000 R10: 0000000000000006 R11: ffffffff803c6d32 R12: fffffffffffffff3 R13: 0000000000008180 R14: 0000010019a5b868 R15: 000000000000000a FS: 0000002a95ec24c0(0000) GS:ffffffff80551b40(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b CR2: fffffffffffffff3 CR3: 0000000000101000 CR4: 00000000000006e0 Process kdm (pid: 18656, threadinfo 00000100143b2000, task 000001000b512a10) Stack: 000001001bf3c120 000001001bf3cc78 0000000000008180 ffffffff801e99c6 0000000000000000 0000010019a5b868 0000000000000000 0000000000000000 0000000000000000 0000000000000000 Call Trace:{reiserfs_create+102} {vfs_create+237} {open_namei+432} {filp_open+39} {get_unused_fd+180} {sys_open+76} {system_call+126} Code: 41 ff 0c 24 0f 94 c0 84 c0 74 08 4c 89 e7 e8 19 00 f6 ff 89 RIP {reiserfs_cache_default_acl+164} RSP <00000100143b3db8> CR2: fffffffffffffff3 This happens 100% of the time, and the workaround is not to mount reiserfs with "-o acl", of course.
