Hello,
I made some tests with Khalid Aziz's patches but I have problems with
SCSI devices reset :
I tried to run kexec on an itanium system with this device :
03:01.0 SCSI storage controller: Adaptec AHA-3960D / AIC-7899A U160/m
(rev 01)
and this one :
03:01.0 SCSI storage controller: LSI Logic / Symbios Logic 53c1030 PCI-X
Fusion-MPT Dual Ultra320 SCSI (rev 08)
I tried on a x86 system with this SCSI device :
02:04.0 SCSI storage controller: Adaptec AIC-7899P U160/m (rev 01)
and eveything works well with a 2.6.15.4 kernel.
On IA64, kexec can not reboot the second kernel.
I tried with a 2.6.15 kernel and Khalid's patch, but I have the same
result :
PCI: Enabling device 0000:03:01.0 (0152 -> 0153)
