Subject: Repeated fd0 messages during boot
Date: Tue, 10 Apr 2012 20:17:59 +0100 [thread overview]
Message-ID: <20120410191759.GD4684@vnl.com> (raw)
This happened after a recent upgrade using an Ubuntu
Precise kernel, 3.2.0-22-generic-pae to be, er, precise.
The machine is an old one. It has a floppy controller but
has no floppy installed. The dmesg shows some floppy related
messages that are not terribly worrisome earlier on:
[ 2.071881] agpgart-sis 0000:00:00.0: SiS chipset [1039/0746]
[ 2.102241] agpgart-sis 0000:00:00.0: AGP aperture is 128M @ 0xe0000000
[ 2.116375] Floppy drive(s): fd0 is 1.44M
[ 2.136428] FDC 0 is a post-1991 82077
[ 2.227141] sis900.c: v1.08.10 Apr. 2 2006
[ 3.111250] sdc: sdc1
[ 3.111838] sd 3:0:0:0: [sdc] Attached SCSI disk
[ 4.523572] Btrfs loaded
[ 17.188579] end_request: I/O error, dev fd0, sector 0
[ 17.313154] REISERFS (device sda1): found reiserfs format "3.6" with standard journal
But around about here, it gets into trouble:
[ 58.907693] ata4.00: configured for UDMA/133
[ 58.907754] ata4: EH complete
[ 60.434537] init: udev-fallback-graphics main process (1063) terminated with status 1
[ 67.164604] end_request: I/O error, dev fd0, sector 0
[ 68.704019] br0: no IPv6 routers present
[ 73.568022] br0: port 1(eth1) entering forwarding state
[ 79.320863] end_request: I/O error, dev fd0, sector 0
[ 79.320883] Buffer I/O error on device fd0, logical block 0
[ 91.488597] end_request: I/O error, dev fd0, sector 0
[ 91.488619] Buffer I/O error on device fd0, logical block 0
[ 103.644762] end_request: I/O error, dev fd0, sector 0
[ 103.644784] Buffer I/O error on device fd0, logical block 0
[ 115.808406] end_request: I/O error, dev fd0, sector 0
[ 115.808425] Buffer I/O error on device fd0, logical block 0
[ 127.976466] end_request: I/O error, dev fd0, sector 0
This continues for a considerable time, ie many minutes. Then the
machine continues booting normally:
[ 1174.164517] Buffer I/O error on device fd0, logical block 0
[ 1174.314178] reiserfs: enabling write barrier flush mode
[ 1174.369389] REISERFS (device sda1): Removing [63554 81060 0x0 SD]..done
[ 1174.369575] REISERFS (device sda1): Removing [63554 51447 0x0 SD]..done
Any idea what is causing this? Kernel bug? Ubuntu patch bug?
