[Martin Benes]

Dobry den,

pouzivam jadro 2.4.19 a server s dvema SCSI - systemovy na aic-7899-36GB
a datovy Adaptec I20-raid 5. Vse bezelo prima, az do doby, kdy jsem vcera
zvetsil o polovinu kapacitu toho raidu (misto 5 18gb , dal 5 36gb).

Pokud nyni pristupuji na sdb, generuje se mi na konzoli stovky hlasek

Warning - running *really* short on DMA buffers

Patrne se tedy jedna o to, ze bude vadny scsi ovladac v jadre ? - ..
kazdopadne

dekuji Martin
