I just booted 2.5.26 to textmode, logged in as root and left it there. After
a while I got this. After that, floppy access etc fails.

I'm not sure how to reproduce it (the machine was idle for hours before it took place), but I'll be happy to test should you come up with a fix. > > After that, floppy access etc fails. > > That would probably be unrelated - the message is just a > warning/debug thing. Well, in that case, here's the kernel log snippet. At the time, I tried something like dmesg > /dev/fd0. And /dev/fd0 should exist - I booted from it (kernel copied onto it, no lilo). The rootfs is on /dev/hdc (cdrom), ext2. No modules, vanilla 2.5.26. And, no I didn't change the floppy in between. --------------------------------------------------------------------------- VFS: Disk change detected on device fd(2,0) generic_make_request: Trying to access nonexistent block-device fd(2,0) (0) Unable to handle kernel NULL pointer dereference at virtual address 0000008c printing eip: c01adc5d *pde = 00000000 Oops: 0000 CPU: 0 EIP: 0010:[<c01adc5d>] Not tainted EFLAGS: 00000082 eax: 00000000 ebx: 00000000 ecx: 00000001 edx: c2adde0c esi: c2adde28 edi: c105f7a4 ebp: c2addde8 esp: c2addde0 ds: 0018 es: 0018 ss: 0018 Process dd (pid: 719, threadinfo=c2adc000 task=c2fa75a0) Stack: c2adde28 c2adde08 c2adde74 c01b7279 00000000 c2adde28 00000000 c2adde10 c01b110c 00000001 00000001 c2adde0c c2adde0c c01b12cf c105f7a4 00000400 00000000 c01152c5 00000000 00000000 c3f2a180 00000000 00000000 00000001 Call Trace: [<c01b7279>] [<c01b110c>] [<c01b12cf>] [<c01152c5>] [<c01b71c0>] [<c01b72d8>] [<c013da13>] [<c01b6e81>] [<c013db0f>] [<c013d589>] [<c013d6b4>] [<c013de17>] [<c01367fe>] [<c0136646>] [<c0136a85>] [<c0109117>] Code: 8b 93 8c 00 00 00 8d 8b 8c 00 00 00 39 ca 74 39 8b 41 04 89 floppy driver state ------------------- now=6216204 last interrupt=521 diff=6215683 last called handler=c01b2d20 timeout_message=lock fdc last output bytes: 0 0 0 0 0 0 0 0 0 8 80 517 8 80 517 8 80 517 8 80 517 e 80 519 13 80 519 0 90 519 1a 90 520 0 90 520 12 80 520 0 90 520 14 80 520 18 80 520 8 80 521 8 80 521 8 80 521 8 80 521 last result at 521 last redo_fd_request at 521 status=80 fdc_busy=1 cont=00000000 CURRENT=00000000 command_status=-1 floppy0: floppy timeout called no cont in shutdown! floppy0: timeout handler died: floppy shutdown Ksymoops: >>EIP; c01adc5d <generic_unplug_device+d/60> <===== Trace; c01b7279 <__floppy_read_block_0+a9/e0> Trace; c01b110c <set_fdc+6c/e0> Trace; c01b12cf <_lock_fdc+14f/160> Trace; c01152c5 <call_console_drivers+65/120> Trace; c01b71c0 <floppy_rb0_complete+0/10> Trace; c01b72d8 <floppy_read_block_0+28/60> Trace; c013da13 <check_disk_change+93/b0> Trace; c01b6e81 <floppy_open+251/450> Trace; c013db0f <do_open+6f/2d0> Trace; c013d589 <bdget+e9/140> Trace; c013d6b4 <bd_acquire+34/90> Trace; c013de17 <blkdev_open+37/50> Trace; c01367fe <dentry_open+1ae/220> Trace; c0136646 <filp_open+66/70> Trace; c0136a85 <sys_open+55/90> Trace; c0109117 <syscall_call+7/b> Code; c01adc5d <generic_unplug_device+d/60> 00000000 <_EIP>: Code; c01adc5d <generic_unplug_device+d/60> <===== 0: 8b 93 8c 00 00 00 mov 0x8c(%ebx),%edx <===== Code; c01adc63 <generic_unplug_device+13/60> 6: 8d 8b 8c 00 00 00 lea 0x8c(%ebx),%ecx Code; c01adc69 <generic_unplug_device+19/60> c: 39 ca cmp %ecx,%edx Code; c01adc6b <generic_unplug_device+1b/60> e: 74 39 je 49 <_EIP+0x49> Code; c01adc6d <generic_unplug_device+1d/60> 10: 8b 41 04 mov 0x4(%ecx),%eax Code; c01adc70 <generic_unplug_device+20/60> 13: 89 00 mov %eax,(%eax) -- v -- v@iki.fi ^ permalink raw reply [flat|nested] 4+ messages in thread
