after further testing the problem seems to be in IRQ SHARING.
in fact, with acpi disabled, once the hisax has got irq 9 (it is not possible 
for card type 36 to change the irq), i can load the ethernet modules
8390 and ne2k-pci for my ethernet PCI NE2000 card, but the ne2k-pci
driver also set its irq=9, so everytime i try to do:

ifconfig eth0 up

i get:

SIOCSIFFLAGS: resource temporarily unavailable

why don't add the irq parameter to the hisax winbond driver and to the
ne2k-pci driver ?

p.s.
my motherboard has pci slot 4 and slot 5 condivided and the isdn card is
on slot 4 while ethernet on slot 5 so one may say "change your 
motherboard", but everything worked fine with previous kernels (ACPI, Hisax,
ethernet)

Please help me.
Many thanx.

my bios irq settings are currently set to AUTO.
i don't know why 3 resources (ne2k-pci, the winbond isdn module and the
acpi) want the same irq 9 whereas there are a lot of free irqs...
the manteiner of the ACPI driver sayd his driver is ok for irq sharing
what about ne2k and winbond isdn ? i don't know how to contact the
manteiners of this drivers

Summarizing the problem
My system load modules in this order:
1) ACPI
2) ISDN (Windbond - HiSax)
3) RealTek PCI NE2000 ethernet

-If I compile the kernel with ACPI on, step 2 fails
-If I compile the kernel with ACPI off step 2 is ok (hisax modules loaded on  
  irq 9) but ne2k-pci conflicts is also assigned to irq 9, correctly loaded
  but with the SIOCFIFFLAGS error and unusable with ifconfig.

My bios only allow me to change irq setting from AUTO to irq X (on slot
4 (isdn) and 5 (eth0) simultaneously). I tried to set it from AUTO to 12
but it didn't resolve the conflict...

The most strange thing is that with previous 2.4.0 test kernels everything
worked fine

Many thanx.

yes it is

> If it is a PCI device, the driver is broken.

in fact this is the most probrably hypothesis of my problems
this reply has been also forwarded to the author of the winbond driver
(a guy from the czech republic) and to cornelius (many thanx for your
comments).
to confirm this hypotesis i can just compile the kernel with both
acpi and ethernet but without the isdn driver. if irq sharing is ok
then the problem must be in the file drivers/isdn/w6692.[ch]
thanx a lot to everybody supporting linux and in particular to
those who are helping me in this tedious problem.

the problems seems to be in the winbond driver (driver/isdn/hisax/w6692.[ch])
i tried to contact the author but the email address doen't exists anymore 
([EMAIL PROTECTED]) could you help me ?
ACPI and NE2000 seems to be ok...

[PATCH] scsi: ignore Synchronize Cache command failures to keep using drives not supporting it

2019-03-17 Thread Guido Trentalancia
Many obsolete hard drives do not support the Synchronize Cache SCSI
command. Such command is generally issued during fsync() calls which
at the moment therefore fail with the ILLEGAL_REQUEST sense key.

Since this failure is currently treated as critical in the kernel SCSI
disk driver, such obsolete hard drives cannot be used anymore (at least
since kernel 4.10, maybe even earlier): they cannot be formatted,
mounted and/or checked using tools such as e2fsprogs.

Because there is nothing which can be done if the drive does not support
such command, such ILLEGAL_REQUEST should be treated as non-critical so
that the underlying operation does not fail and the obsolete hard drive
can be used normally.

Of course, using such hard drives which do not feature the Synchronize
Cache SCSI command implies a very high risk (or maybe even certainty) of
data loss in case of power cuts, USB cable disconnects and so on -
SO YOU HAVE BEEN WARNED - IN DOUBT, UPGRADE TO A NEWER HARD DRIVE !!!

[PATCH v2] scsi: ignore Synchronize Cache command failures to keep using drives not supporting it

2019-03-20 Thread Guido Trentalancia
Many obsolete hard drives do not support the Synchronize Cache SCSI
command. Such command is generally issued during fsync() calls which
at the moment therefore fail with the ILLEGAL_REQUEST sense key.

This second version of the patch (v2) disables the Write Cache feature
as a precaution on hard drives which do not support the Synchronize Cache
command and therefore the cache flushing functionality.

Although the Write Cache is disabled (v2) when using such hard drives
which do not feature the Synchronize Cache SCSI command there is still
some risk of data loss in case of power cuts, USB cable disconnects and
so on: YOU HAVE BEEN WARNED - THE DRIVE MANIFACTURER SHOULD HAVE BEEN
WARNED YOU IN THE FIRST PLACE - IN DOUBT, UPGRADE TO A NEWER HARD DRIVE !!
