Subject[BUG] 2.4.20-BK
Date
Hi Alan,

using 2.4.20-BK tree gives me:

flushing ide devices: hda hdd

at reboot time in an endless loop drawing over the screen. No reboot will be
made, I have to do that either by sysrq-b or reset button.

Using:

[*] PCI IDE chipset support
[*] Generic PCI bus-master DMA support
[*] Use PCI DMA by default when available
<*> Intel PIIXn chipsets support
[*] IGNORE word93 Validation BITS

root@codeman:[/] # hdparm -i /dev/hda

/dev/hda:

Model=MAXTOR 6L060J3, FwRev=A93.0500, SerialNo=663219752652
Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs }
RawCHS=16383/16/63, TrkSize=32256, SectSize=21298, ECCbytes=4
BuffType=DualPortCache, BuffSize=1819kB, MaxMultSect=16, MultSect=16
CurCHS=4047/16/255, CurSects=16511760, LBA=yes, LBAsects=117266688
IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120}
PIO modes: pio0 pio1 pio2 pio3 pio4
DMA modes: mdma0 mdma1 mdma2
UDMA modes: udma0 udma1 udma2 udma3 udma4 *udma5 udma6
AdvancedPM=no WriteCache=enabled
Drive conforms to: ATA/ATAPI-5 T13 1321D revision 1: 1 2 3 4 5


BTW: The attached patch is needed to build the 2.4.20-BK tree successfully
because "local_irq_*" is missing and ld complains about undefined
reference at linking time.

Any hints to fix that flushing ide bla foobar thing?

TIA!
